Force and Motion Review

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

If John walks 5 km in 10 minutes, what is his speed in km/h?

Back

30 km/h

Front

What is a force?

Back

A push or pull that can change the motion of an object.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What happens to an object in motion when no forces act on it?

Back

It continues to move at a constant velocity.

Front

What are the three possible effects of a single force acting on an object?

Back

The object can speed up, slow down, or remain at rest.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect the motion of an object?

Back

More mass means more inertia, making it harder to change the object's motion.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the object's motion.
