# Does force depend on area?

## Does force depend on area?

Friction is a contact force when two surfaces interact. Notice that both of these friction formulas only depend on the coefficient of friction and the normal force. It does not depend the area of contact; it doesn’t depend on the sliding speed.

## What is the effect of mass on friction?

An object of large mass is pulled down onto a surface with a greater force than an object of low mass and, as a consequence, there is greater friction between the surface of the heavy object than between the surface and the light object.

## Does frictional force increase with mass?

As the mass increases, the static friction increases. This is because the normal force increases as the mass increases.

## Why does mass not affect centripetal acceleration?

Where is the centripetal acceleration on an object, is the velocity of an object, and is the radius in which the object moves in a circle. We can see that mass does not play a role in the centripetal acceleration of an object, so no matter what happens to the mass, the centripetal acceleration remains the same.

## Does the puck’s mass have any effect on its acceleration?

Does the puck’s mass have any effect on itsacceleration? Explain. No. The puck does not move as I move the slider.

## How does centripetal force affect speed?

As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. The force can indeed accelerate the object – by changing its direction – but it cannot change its speed.

## When the mass increases the acceleration will?

Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. Therefore, if you double the force you double the acceleration. If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.
