Forces and Motion Quiz

What is a force?

• A push or pull on an object
• A type of energy
• A measure of speed
• A change in direction

Which of the following is an example of an unbalanced force?

• A book resting on a table
• A car accelerating down a hill
• A ball sitting still
• A person holding a heavy box

What does motion describe?

• A change in an object's position
• The speed of an object
• The force acting on an object
• The weight of an object

What is velocity?

• Speed in a specific direction
• The distance traveled
• The time taken to travel
• The change in speed

According to Newton's First Law, what happens to an object at rest?

• It stays at rest unless acted upon by a force
• It starts moving on its own
• It will eventually fall
• It will change direction

What does Newton's Second Law state?

• Force equals mass times acceleration
• For every action, there is an equal reaction
• An object in motion stays in motion
• Mass is always constant

If the mass of an object increases, what happens to the force needed to move it?

• It decreases
• It stays the same
• It increases
• It becomes zero

What is an example of Newton's Third Law of Motion?

• A ball rolling down a hill
• A rocket launching into space
• A swimmer pushing against the water
• A car stopping at a red light

Which of the following describes balanced forces?

• Forces that cause a change in motion
• Forces that are equal in size and opposite in direction
• Forces that only act on moving objects
• Forces that are always unbalanced

What is acceleration?

• A change in an object's position
• A change in an object's speed
• The speed of an object
• The force acting on an object
