How does the height of the ramp effects the distance the car travels?

1)The work done by gravity on the car is independent of horizontal distance but is proportional to its change in height. this means that the potential energy that is converted to kinetic(motion) energy is all that has changed :
Change in potential energy can be found by a simple formula : m*g*h where m is the mass, g is gravitational acceleration (9.8m/s) and h is the change in height. if a car weighs 1000kg and the ramp is 2m high, the kinetic energy will be roughly 20000kg*m/s. and kinetic energy can be found by 1/2mv^2 we solve for v (velocity, speed) and get 6.324m/s or 22km/h. Again, if we don't count slope or friction than the slope of the ramp does not matter.
2)Because of gravity the car is forced downward. The higher the ramp, the more distance gravity has to apply to the car. Therefore, the higher the ramp, the further the car will travel.
3)The higher the ramp, the faster the car goes when it reaches the bottom. The distance depends on speed and friction. With no friction the car would keep going forever.

∙ 11y agoYes the higher you go the more energy (speed) is converted to GPE (gravitational potentional energy) therefore if the speed is converted then the speed decreases
Hope this helps and has not just completely confused you :)

You are an avid skateboarder and just skated down a ramp You want to find the distance you traveled The height of the ramp at its tallest part is 40 inches and the horizontal length is 81 inches Ca?
You are an avid skateboarder and just skated down a ramp. You want to find the distance you traveled. The height of the ramp at its tallest part is 40 inches and the horizontal length is 81 inches. Calculate the distance, to the nearest whole inch, you traveled down the ramp.
When the mover pushes the box up the ramp there is friction between the box and the ramp What is the efficiency of the ramp?
It depends on the mass of the box, the force exerted, the total displacement and the height the box was moved.
How do you calculate the ideal mechanical advantage of an inclined plane?
Its the reciprocal of the sine of the ramp angle. > 1 / ( sin ( ramp angle ) )
When you use a ramp what happens to the distance over which you exert force?
The distance is longer than the lift or the drop, but the force you need is less than the weight of the load.
A clerk can lift containers a vertical distance of 1 meter or can roll them up a 2 meter-long ramp to the same elevation With the ramp the applied force required is about?
The same amount
Name 2 factors the affect the distance taken for a toy car to stop after rolling down a ramp?
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.
Does the distance a toy car travels up a ramp affect its speed?
Yes.
Does ramp height effect a model cars distance?
yes
Did the height of the ramp increase the distance the car rolled?
if the ramp forms a very steep gradient, definately the car will roll for a longer distance. On the contrary, if the gradient formed by the ramp is gentle, then it will roll for a shorter distance

How would the input force needed to push a wheelchair up a ramp change if you increase the height of the ramp but not its length?
The input force would increase as the height of the ramp increased. It wouldn't matter the distance. Ask me another one.
What is the relationship between the differences in height of a ramp and the total distance an object can travel starting at each height?
This is a bad question.

How does the length of a car affect the distance a car travels down a ramp?
In terms of physics, the length makes no difference.
How does a ramp make it easier to move heavy objects?
What a ramp does is trade distance for height. So it's not easier to move an object so much as it's easier to lift an object with a ramp.

What is a ramp that decreases the force required to move an object while increasing the distance the object travels?
simple machine
