• 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.

• 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?
