2. Which hill is faster to go down? Taller or shorter?
When an object's point is taller the thing that is going down it will go faster than when the point is lower.
EXAMPLE: The object is the tennis ball if you drop it down the higher hill it will be faster than if you drop it down a shorter hill.

3. Picture of ramp
This is a picture of a hill that will make your vehicle increase and decrease speed.

4. When gliding down a slope or hill will gradually increase your speed because when you're going down a steep slope or hill you're speed increases.

5. How long it takes for a hot wheels car to get down a ramp.

6. How the height of ramps affect the speed or an object.
To investigate into how the height of a ramp affects the speed of a toy car rolled down a hill or slope because the higher the ramp the more Gravitational potential Energy (GPE), the more kinetic energy converted and the car will go faster. So the ramp increases, the velocity will also increase. If you also decrease the height or a ramp your velocity will decrease as well as your speed.

7. GLOSSARY INCREASE- increase is where something gets higher or faster.
DECREASE- decrease is where something gets lower or slower.
SLOPE- slope is where one side is higher than the other.
VELOCITY- velocity is the speed of something in a given direction.
ENERGY- energy is how much speed is going into the object.
SPEED- speed is how fast an object is going.
