Forces and Motion Concepts

Front

What is Inertia?

Back

Inertia is a property of matter that describes an object's resistance to changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What happens when two objects collide with the same speed?

Back

According to Newton's 2nd Law, when two objects collide with the same speed, they will bounce backwards off each other.

Front

What will an object at rest do until acted upon by an outside force?

Back

An object at rest will stay still until acted upon by an outside force.

Front

What force acts on you when you are falling?

Back

The force of gravity acts on you when you are falling.

Front

Which factor does NOT affect the force of gravity on you?

Back

Your height does not affect the force of gravity on you.

Front

What is the definition of Force?

Back

A force is a push or pull on an object that can cause it to change its velocity (speed or direction).

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is the formula for calculating Force?

Back

Force (F) is calculated using the formula F = mass (m) x acceleration (a).

Front

What is the effect of mass on inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in its motion more than a lighter object.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.
