Amplify Force and Motion Unit Review

Front

What is the effect of force on an object's velocity?

Back

A force is required to change the velocity of an object, meaning it can cause the object to speed up, slow down, or change direction.

Front

What happens when the same force is applied to different masses?

Back

The object with the smaller mass will experience a larger change in velocity compared to the object with the larger mass.

Front

What is the definition of 'exert' in the context of force?

Back

To exert means to apply or put forth a force on an object.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to move or 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 Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is a balanced force?

Back

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