Amplify Force and Motion Unit Review

Front

What is required to change the velocity of an object?

Back

A force is required to change the velocity of an object.

Front

What is a push or pull that can change the motion of an object?

Back

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

Front

In a crash, which crash experiences a stronger force on the satellite?

Back

In Crash 1, the force exerted by the black asteroid would have been stronger, so the force on the satellite would also have been stronger.

Front

In which crash did the rubber duck experience a stronger force?

Back

In Crash two, the force on the orange boat is stronger, indicating the rubber duck experienced a stronger force.

Front

What is the definition of force?

Back

Force is an interaction that causes an object to change its velocity, direction, or shape.

Front

What is the relationship between mass and force?

Back

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

Front

What is balanced force?

Back

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

Front

What is unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to accelerate or change direction.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, making it harder to change its motion.
