An experiment on the effects of weight on speed and friction
Friction experiment: measure coefficient of friction with a scale by ron kurtus (revised 16 november 2012) friction is a resistive force caused when two objects are in contact with each other. Welcome to the ask an expert forums we're happy to help you i'll respond here, and then make a post to the other topic you started and any friction effects caused by interaction of ramp and wheels but only with a smaller effect (doubling the weight increasing speed only a little probably means the weight helps overcome friction but. Weight affects friction in that friction is directly proportional to the weight of the load one is moving if one doubles the load being moved, friction increases by a factor of twofriction is the force that opposes motion of one object over another. Friction is directly proportional to the normal force of an object basically the speed of the object in the x direction does not effect the normal force in the y direction of an object to any discernable degree.
As it turns out, the only thing that impacts friction is the type of surfaces interacting and the weight of the object heavier objects have a larger frictional force. Forces affect the motion and speed of a football in the game, and different forces can help or hinder motion in the game at different times some forces are in direct contact with objects, while other forces are not. Friction lab strand force 4 tell students that they will be designing an experiment to test the effect of friction on different objects experiment and then the completion of that friction experiment if you have time.
- investigating the effect of mass and speed of a moving object on its stopping time the investigation is about the mass and speed of a moving object and how this affects its stopping distance due to the changes in energy needed to brake. Obviously pouring oil onto your hand crafted friction boards is not recommended, however an empty tray with a small amount of oil or silicone beads may be used to good effect sleds can be simply made from a piece of metal sheet of approx 10 x 5cm. Does mass affect friction yes, it affects it because the heavier an object is the more friction there will be, for example, if a mouse was big and you try to push it it will be harder because there is friction acting on it. Friction is defined as the resistance force between two solid surfaces that are rubbing against one another in skating sports, such as ice hockey, figure skating and speed skating, different levels of friction are created by skaters to speed up or stop on the ice. Relates the magnitude of the force of friction to the magnitude of the normal force the normal force is always directed perpendicular to the surface, and the friction force is always directed parallel to the surface but when you double the length of an object, you halve the force on each square centimeter, because less weight is above it.
Effect of sliding speed and normal load on friction and wear property of an aluminum disc sliding against stainless steel pin to do so, a pin-on-disc apparatus was designed and fabricated. The resultant force and balanced forces forces have size and directionon diagrams they are represented by arrows, in the direction the force acts the length of the arrow represents the size of the force when an object has several forces acting on it, the effect is the same as one force in a certain direction. Experiment 5 ~ friction purpose: in this lab, you will make some basic measurements of friction first you will measure the coefficients of static friction between several combinations of surfaces using a heavy block and a set of hanging masses. Friction and speed friction friction is the force that resists motion when the surface of one object comes into contact with the surface of another in a machine, friction reduces the mechanical advantage, or the ratio of output to input: an automobile, for instance, uses one-quarter of its energy on reducing friction. Experiment 4 coefficient of sliding friction in this experiment you study the force ffric including the relative speed of the surfaces and the surface area of contact you will the total weight of the block is equal in magnitude to the normal force, or f n.
An experiment on the effects of weight on speed and friction
This is an experiment based on showing the effects of friction - it is called the mu of the shoe and requires students to find and calculate the coefficient of friction of their shoe across different frictions with different masses. The effects of weight and contact area on friction are complicated because there are two major mechanisms of friction at work the classical view of friction is that it is caused solely by surface irregularities, called asperities, and that weight correlates directly with the amount of friction that occurs. Simple friction experiments anna hajdusianek friction increases proportionally to the body weight another scholar who has studied the friction was guillaume amontos he noted that the friction is caused by rough another simple experiment that shows the effect of the friction is rubbing the hands. Friction, experiment and theory things as the area of contact and the speed of motion let us study the question 4 if you still have some time left, determine experimentally the effect of surface area and velocity upon the coefficient of friction of wood-on-wood discuss your results 43.
- Factors affecting friction experiment i have to design an experiment to determine how certain factors (weight, surface area, and speed) affect the force of friction.
- However we had to change our experiment to the different surfaces that apply more friction and would therefore change the velocity because other teams told us that mass doesn't affect velocity were they correct in telling us that mass doesn't affect velocity or vice versa.
- This is the speed of a body in a given direction and is measured in metres per second (m/s) reaction rn = weight w then limiting friction force is f f = commander david scott's hammmer and feather experiment from apollo 15 how to add and resolve force vectors.
An increase in an object's weight also increases resistive forces, such as friction, which makes it more difficult for an object to gain speed at rest and increases the tendency for the object to lose speed while in motion. How do different surfaces affect the momentum of marbles simply put, is the mass of a moving body times its velocity, or speed in a specific direction if friction is not a factor, momentum will pass from one object to a second and then to a third at a constant rate a stopwatch and different surfaces you can conduct the experiment on. The effect of surface texture – science fair which ramp surface will a marble roll the farthest on the purpose of this experiment is to find out whether the texture of a surface will affect the distance rolled by a marble, and if so, which ramp surface a marble will roll the farthest on. Start studying motion, forces, friction, gravity learn vocabulary, terms, and more with flashcards, games, and other study tools the effect of gravity on an object's mass equal and opposite reaction force what is the speed of an object that travels 300 km in 6 hrs 50km/hr what is the average speed of a train that travels 300 km in.
