Force and Motion Vocabulary Quiz

What is force?

• A type of energy

• A push or pull upon an object resulting from the object's interaction with another object.

• The speed of an object

• The color of an object

What is the unit of force?

• Kilogram (kg)

• Second (s)

• Newton (N)

• Meter (m)

What is inertia?

• Speed of an object

• Ability to move freely

• Force applied to an object

• Resistance to change in motion

What is the difference between mass and weight?

• Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

• Mass and weight are the same thing.

• Mass is measured in pounds, while weight is measured in kilograms.

• Mass is the force exerted on an object, while weight is the amount of matter in an object.

What is Newton's first law of motion?

• An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• An object in motion will change direction without any external force

• An object at rest will start moving on its own

• An object in motion will slow down and eventually stop

What is Newton's second law of motion?

• Velocity is equal to mass times acceleration

• Energy is equal to mass times acceleration

• Acceleration is equal to force times mass

• Force is equal to mass times acceleration

What is Newton's third law of motion?

• Newton's third law of motion is about the relationship between force and acceleration.

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

• Newton's third law of motion states that action and reaction are not equal.

• For every action, there is a smaller and opposite reaction.

What is friction?

• Friction is the force that increases the speed of an object

• Friction is the force that has no effect on the motion of an object

• Friction is the force that helps the motion of an object

• Friction is the force that opposes the motion of an object when it is in contact with another object or surface.

How does air resistance affect motion?

• It has no effect on the motion of an object

• It slows down the motion of an object

• It speeds up the motion of an object

• It causes the object to change direction

A force that slows down or stops motion when objects rub together is ___________________.

• Gravity

• Friction

• Motion

• Magnetism
