Yes.
yes This is because of the fact that gravity is a measure of acceleration. The longer the car has to accelerate the faster is will be by the end.
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.
In terms of physics, the length makes no difference.
Changing the slope of the ramp will affect the speed of the vehicle going down it.
Yes. The degree and slant of the ramp does affect the speed of the car
No.
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
Yes. The height of the ramp does affect the speed going down it the higher the ramp the faster the car goes down it
Yes.The higher the ramp the faster.
Yes,if you are going at 100 mph and you go down a steep hill your speed on speedometer does not go higher but your car actually gains speed no it does not, the height of the ramp affects the distance ,not the speed.Laws of physics apply here.
At the bottom of the ramp, the higher the ramp the faster the speed, ignoring frictionl forces The speed varies as the square root of the height
Yes, it does. The further up a ball is placed on a ramp, the greater the distance the ball travels. If launched from a lower starting position, then the ball shall travel a shorter distance. This is all true under Newton's second law, which states that Force = mass * acelaration(F= m*a). If the ball has to move something, i.e. a cup, then the rule applies as well.
