See the discussion box for the options. The answer is A, D and E.
Speed is how fast something is moving. When to things are traveling at the same speed and rubbing together, they can cause friction.
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.
Same way it affects all structures - heat and sound is produced, and some material is lost due to ablation (being rubbed away).
A contact force, such as friction. If a car wheel wasn't on the ground there couldn't be friction. A non-contact force could be magnets, the two magnets don't need to touch to repel or attract :)
Grip is a combination of pressure and friction. The more pressure one exerts upon an object the greater the friction and then the better grip one would have on the object in hand. Same goes for anything that can grip like tires, shoes, etc. Another thing that affects grip is the pattern of the surface applying the pressure, different patterns will exert the force differently.
No, weight does not directly affect the amount of friction between an object and a surface. The factors that affect friction are the nature of the surfaces in contact and the force pushing them together. The normal force, which is perpendicular to the surface, is what influences the frictional force, not the weight of the object.
By using kinetic friction
Weight affects friction by increasing the force pressing the surfaces together, resulting in more friction. Mass does not directly affect friction, but it influences the normal force, which in turn affects friction. Generally, higher weight or mass leads to higher friction.
no, friction just changes the motion of an object.
Yes, weight does affect friction. With an increase in weight, there is usually an increase in the force pressing objects together, resulting in higher friction between the surfaces. This means that heavier objects may experience greater friction compared to lighter objects.
if there is friction on the hill it will slow you down
it affects motion by friction a friction pull it down or up
Friction can have an impact on velocity ratio by reducing the efficiency of a system. Friction can transfer energy into heat, causing a loss in velocity and making it more difficult to maintain a consistent velocity ratio. Reducing friction through lubrication or other means can help improve the velocity ratio.
Friction acts in the direction opposite to that of the net force acting on the object.
Friction affects most every thing. In a mechanical metronome you would not need a power source if there were no friction.
it affects it by the contact with the car
it is usually greater than static friction
