Front

What is the Law of Inertia?

Back

The Law of Inertia states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force.

Front

What happens to a stationary bumper car when another bumper car collides with it?

Back

The stationary bumper car is set in motion due to the external force from the colliding bumper car.

Front

If two boxes are pushed with the same force, which will accelerate faster: a 1kg box or a 100kg box?

Back

The 1kg box will accelerate faster because it has less mass.

Front

What happens to acceleration if you increase the force on an object?

Back

The acceleration increases.

Front

Why does an 18-wheeler have more inertia than a bicycle?

Back

An 18-wheeler has more inertia because it has more mass.

Front

What type of forces cause a change in an object's motion?

Back

Unbalanced forces cause a change in an object's motion.

Front

What is the formula for calculating acceleration?

Back

Acceleration = Force / Mass.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms.

Front

What is force?

Back

Force is a push or pull on an object, measured in newtons (N).

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when one bumper car hits another, causing it to move.
