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.
The speed of a ball rolling down a ramp affects the distance it travels because a faster speed typically results in the ball covering a greater distance before coming to a stop. This is due to the increased kinetic energy of the ball at higher speeds, allowing it to overcome friction and air resistance more effectively.
In terms of physics, the length makes no difference.
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.
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.
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
Air resistance against the car as it travels and the friction of the wheels against the ground slows it down and so reduces the toy car's potential travelling distance The weight of the car\on the car, the slope of the ramp and the material the car lands on or on the ramp
No.
Yes, the height of a ramp can affect the speed of a marble. The higher the ramp, the more potential energy the marble has, which can be converted into kinetic energy as it rolls down the ramp. Therefore, a higher ramp may result in a faster speed for the marble.
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,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.
