the steeper the ramp, the farther the car goes. if your ramp is flatter, it won't go as far.
No.
The larger the angle of the ramp, the faster the car will go down it.
One factor is the height of the ramp. The higher the height of the ramp the further the car travels. Another factor is the surface of the ramp. With a rough surface on the ramp e.g sand paper the car travels a short distance. With a lubricated surface on the ramp e.g Vaseline the car will travel a very long distance.
if its steeper it'll go faster
yes because Gravity is pulling it down and the heavier the mass the farther it will travel down the ramp. The heavier it is the more gravity has to pull down
The velocity increases due to the fact, the ramp is facing downwards in a certain angle. The longer the ramp, the faster the cart will travel!
in our experiment the higher angle 60 degrees slow the car down because of the severity of impact where slope/ramp touch the floor. the middle angle 30 degrees had best result with smoothest transition.
Yes.
it affects speed because it could make it go slower or faster
No
The cart will go faster if the angle increases.
The angle of inclination.
