Force and Motion Review

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

What happens to a rolling ball on grass compared to a smooth surface?

Back

A rolling ball will slow down more on grass than on a smooth surface due to increased friction.

Front

What is force?

Back

Force is a push or pull on an object that can cause it to move, stop, or change direction.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is required to move it.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between surfaces.

Front

What is the effect of applying the same force to two identical objects?

Back

If the same force is applied to two identical objects, they will move the same distance.

Front

What is the effect of stopping a moving cart suddenly?

Back

The contents of the cart, like books, will continue moving forward due to inertia.

Front

What type of surface would require the most force to move an object?

Back

A rough or heavy surface, like a wagon full of bricks, requires more force to move.
