6.8A- A ball is sitting at the top of a ramp. As the ball rolls down the ramp, the potential energy of the ball decreases. What happens to the potential energy as the ball moves?
It is lost as gravitational energy.
It is destroyed as the ball moves.
It is converted to kinetic energy
It is used to make the ball slow down.
Which picture of the rock has the LEAST amount potential energy and the GREATEST amount of kinetic energy? Read the answers carefully!
Rock A
Rock B
Rock D
Rock E

6.8B- A box and forces are shown below. A box rests motionless on the ground. One student is pushing the box to the right with a force of 2 Newtons. The other student is pushing to the left with a force of 5 Newtons. In which direction and with what type of speed will the box move?
It will move left
It will move to the right
It will float in the air
It will not move
6.8B- An image of a toy rocket and forces are shown below. Assuming the only two forces on the toy rocket are lift and gravity, which of the following combinations would result in the rocket moving upward?
Lift= 5 Newtons / Gravity = 5 Newtons
Lift = 3 Newtons / Gravity = 4 Newtons
Lift = 5 Newtons / Gravity = 4 Newtons
Lift = 4 Newtons / Gravity = 4 Newtons
6.8E- The diagram shows an investigation in a science classroom.
Students pulled the same mass up an inclined plane propped up on five blocks, then six, seven, and eight blocks. Each time, they use a spring scale to measure the forces needed to pull the mass up the inclined plane. This investigation can show how which of the following affects the force needed to move an object up an inclined plane?
The mass of the object
The height of the inclined plane
The length of the inclined plane
The surface area of the object
6.8E- How could students find out whether a short ramp or a long ramp would require less force to use? Measure the amount of force it takes to move —
an object up two ramps with the same height, but different lengths
an object up two ramps with equal heights and equal lengths
an object up two ramps with the same length, but different heights
one object up a ramp and a larger object up an identical ramp
If a car is moving on a highway at 70 kilometers per hour, going south, and then turns to travel 70 kilometers per hour, going east, what happens to its speed and velocity?

One advantage of solar and wind power over fossil fuels is that
wind and solar are presently much less expensive than fossil fuels.
wind and solar come from natural processes and fossil fuels do not.
wind and solar are nonrenewable resources and fossil fuel are renewable.
wind and solar are continuously renewable and fossil fuels take millions of years to be formed.
