Amplify Force & Motion Mid Unit Review

Front

What are the five ways an object's motion can change?

Back

Start, stop, change direction, speed up, slow down.

Front

What is a force?

Back

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

Front

What happens to an object when a force is applied?

Back

The object's motion can change, including starting, stopping, speeding up, slowing down, or changing direction.

Front

If two objects have the same mass, how can they experience different forces?

Back

They can experience different forces if they are pushed or pulled with different strengths or directions.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

How does friction affect motion?

Back

Friction opposes motion, making it harder for an object to start moving or to keep moving.

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time.

Front

What is the difference between speed and velocity?

Back

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

Front

What is inertia?

Back

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

Front

How can you determine which object experienced the strongest force?

Back

The object that changes speed the most or changes direction the most experienced the strongest force.
