What is it called when two objects slide past each other?

What is it called when two objects slide past each other?

Term. sliding friction. Definition. the force that opposes the motion of two surfaces sliding past each other.

What is it called when the only force acting on an object is gravity?

8.5 What is Free Fall? When the only force acting on an object is gravity, the object is said to be in free fall. The force of gravity causes the object to accelerate. Free fall is motion where the acceleration is caused by gravity.

What is an object’s collision strength called?

Momentum. An object’s “collision strength.” (P=mv) Impulse. The amount of momentum an object gains and/or loses. (

What do you call the tendency of an object to resist a change in motion?

Inertia = tendency of an object to resist changes in its velocity. An object at rest has zero velocity – and (in the absence of an unbalanced force) will remain with a zero velocity; it will not change its state of motion (i.e., velocity).

What is the force that opposes motion?

Friction is a force that opposes motion. It is present whenever two surfaces rub over each other, such as when you rub your hands together, or when you apply the brakes on a bike or in a car. Friction also prevents an object from starting to move, such as a shoe placed on a ramp.

Why can free fall occur only where there is no air?

An object is in free fall only if gravity is pulling it down and no other forces are acting on it. Because air resistance is a force, free fall can occur only where there is no air.

What are the 3 types of collision?

There are three different kinds of collisions, however, elastic, inelastic, and completely inelastic. Just to restate, momentum is conserved in all three kinds of collisions. What distinguishes the collisions is what happens to the kinetic energy.

Is inertia The cause why objects maintain their state of motion?

All objects resist changes in their state of motion. All objects have this tendency – they have inertia. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
