Force & Motion Unit Review (Amplify)

Front

What is force?

Back

A force is a push or pull that can cause an object to change its velocity.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is velocity?

Back

Velocity is speed in a particular direction.

Front

What happens when two objects collide?

Back

Both objects exert equal and opposite forces on each other.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What is the relationship between mass and force?

Back

The more massive an object is, the more force is required to change its motion.

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 force?

Back

Force = mass x acceleration (F = m x a).

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes direction.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.
