An object travels 5 meters in 1 second. Then travels 10 meters in 2 seconds, next it travels 15 meters in 3 seconds. Which best describes the motion of the object?

• it is going faster

• it is slowing down

• it is moving backwards

• it is moving at a constant speed

Which describes the movement of the object?

• the object speeds up as it moves

• the object starts and ends at the same place

• the object moves at a constant speed then slows doen

• the object moves at a constant speed

a ball is kicked across a sidewalk and onto a road covered in small rocks. Which best describes the effect the rocky road will have on the ball?

• the rocky road will decrease the speed of the ball because of its mass

• the rocky road will increase the speed of the ball because of it mass

• the rocky road will increase the speed of the ball because of friction

• the rocky road will decrease the speed of the ball because of friction

Two balls of similar shape and size, one weighing 1 kg. and the other 2 kg. are both dropped from the top of a ladder at the same time. Which ball will hit the ground first?

• Gravity will cause both to hit the ground at the same time

• friction will cause both to hit the ground at the same time

• the 2 kg ball will hit the ground first because it has more mass than the 1 kg ball

• the 1 kg ball will hit the ground first because it has less mass than the 2 kg ball
