Forces and Motion Test Review

Front

What is the definition of momentum?

Back

Momentum is defined as 'Mass in Motion.'

Front

What is a push or pull called?

Back

A push or pull is called a 'force.'

Front

What does Newton's 1st law of motion state?

Back

Newton's 1st law states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What two factors does the momentum of an object depend on?

Back

The momentum of an object depends on its 'mass and velocity.'

Front

Which has more inertia: a truck, an ant, a cat, or a skateboard?

Back

A truck has more inertia than the other options.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating momentum?

Back

The formula for momentum (p) is p = mass (m) × velocity (v).

Front

What is a force?

Back

A force is a push or pull that can cause an object to accelerate.

Front

What is the relationship between mass and acceleration according to Newton's 2nd law?

Back

According to Newton's 2nd law, force equals mass times acceleration (F = m × a).

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of objects, causing them to slow down or stop.
