Laws of Motion Vocab. Lesson

Multiple Choice

What is the significance of balanced forces in everyday life?

• They help objects move faster

• They keep objects at rest or moving at constant speed

• They always cause objects to change direction

• They increase the weight of objects

Multiple Choice

Collision is transfer of energy between objects by striking or hitting with any amount of force.

• True

• False

Multiple Choice

Which of the following BEST describes a force?

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

• A type of energy

• A measure of temperature

• A form of matter

Multiple Choice

How does friction affect the motion of objects?

• It resists the motion of objects sliding across each other

• It increases the speed of moving objects

• It causes objects to float

• It makes objects invisible

Multiple Choice

How does inertia affect the motion of a soccer ball when it is kicked?

• No force was applied to the ball.

• The ball moved because of the unbalanced force of the kick.

• The soccer ball will not move.

Multiple Choice

Fill in the blank: The change in an object's position with respect to time is called ___.

• motion
• force

• inertia

• None of these

Multiple Choice

Which of Newton's laws states that an object at rest stays at rest, or an object in motion stays in motion, unless acted upon by an unbalanced force?

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Law of Universal Gravitation

Multiple Select

Select ALL that apply: According to Newton's second law of motion, which factors affect the acceleration of an object?

• The object's mass

• The force applied to the object

• The color of the object

• The object's shape

Multiple Choice

Which of the following statements correctly describes Newton's third law of motion?

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

• Objects at rest stay at rest unless acted upon by a force

• Acceleration depends on mass and force

• Friction resists motion between surfaces

Multiple Choice

Newton's third law states that for every action, there is an equal and opposite ___.

• gravity

• inertia

• reaction

• None of these

Multiple Choice

What affects the motion of an object? Example: kicking a soccer ball.

• Balanced Force

• Gravity

• Unbalanced Force

• Friction

Multiple Choice

How do balanced forces affect the motion of an object?

• They change the direction of the object

• They increase the speed of the object

• They do not change the motion of the object

• They decrease the mass of the object
