The larger the angle of the ramp, the faster the car will go down it.
Changing the slope of the ramp will affect the speed of the vehicle going down it.
Yes. The height of the ramp does affect the speed going down it the higher the ramp the faster the car goes down it
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 depends on the speed but it slows it down.
No slope is the angle at which a surface goes up or down.
It would affect its speed because the weight of the car is gonna slow it down
Yes it would. Speed will depend on Weight of the ball, Incline angle, Friction, and air pressure.
when light rays enter a new medium in a new angle it may speed up or speed down
The car's mass should have no effect on that speed.
Going down with temperature means going down with the speed of sound. Here is an easy calculator to test that: Scroll down to related links and look at "Speed of Sound Calculator".
Because a higher ramp gives more potential energy than a shorter one.
