  • AMarie Curie
  • BSir Isaac Newton
  • CThomas Edison

Q2:

can be a push or a pull.

  • AA motion
  • BA force
  • CGravity

Q3:

What word means to “force backward?”

  • ARepel
  • BGravity
  • CMotion

Q4:

What is another name for a forward force?

  • APush
  • BPull
  • CFriction

Q5:

Olivia is pushing Victoria on the swing.

How can Olivia make her friend on the swing go higher?

  • ABy pushing less
  • BBy pushing harder
  • CBy pushing faster

Q6:

  • BThe forces are balanced.
  • CThe sister is pulling harder.

Q7:

What word describes how the pull of gravity on an object is measured?

  • AForce
  • BWeight
  • CMotion

Q8:

Newton’s first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Which of the pictures shows an object in motion?

  • A(1)

  • C(2)

Which picture shows an object with balanced forces acting on it?

  • A(2)
  • B(3)
  • C(1)

Q9:

Isabella and Madison are testing whether the height of the ramp increases the velocity of their cars.

What does velocity mean?

  • AThe speed of an object in a given direction
  • BThe distance that an object travels

Q10:

What is the name of the force that makes the soccer ball fall down toward the earth?

  • AFriction
  • BGravity
  • CMagnetism

Q11:

The picture shows two children riding their scooters.

What force is needed to create motion (or movement) on a scooter?

  • APush
  • BGravity
  • CPull

How can the children increase the speed at which their scooters travel?

  • ABy keeping the amount of push the same
  • BBy increasing the amount of push on the scooter
  • CBy increasing the amount of pull on the scooter

Q12:

What affects the distance that the ball travels?

  • AThe type of soccer cleats the player is wearing
  • BHow tall the soccer player is
  • CThe amount of force used to kick it
