The amount of friction depends on two things: 1) the surface of the two objects and 2) the force pressing the surfaces together. So, the least amount of friction the (a)   ​ an object will move and the more the friction the​ (b)   an object will move.

• faster
• slower

• distance

• mass

• weight

If a ball is rolling down a hill, the faster the ball moves and the heavier the ball is then the more kinetic energy it has. So, what must be true about the ball?

• The ball has the most kinetic energy while it is rolling.

• The ball has the most kinetic energy when it stops rolling.

• The ball has potential energy

• The ball has no kinetic energy

Gravity is a type of force that is always acting on us and this is due to mass, which is a measure of the quantity of matter. So, if you had 3 sheets of paper: 1) a crumbled piece of paper, 2) a paper airplane, and 3) a unfolded sheet of paper. Which one would drop to the ground faster?

• the crumpled up paper

• the paper airplane

• the unfolded sheet of paper
