Divide the height of the ramp by the length of the ramp (rise over run).
a ramp is a flat surface which
To find the efficiency of a ramp, you would calculate the output work (weight lifted) divided by the input work (force applied). The formula for efficiency is (Output Work/Input Work) x 100%. A more efficient ramp would require less input work to lift a certain weight.
It works like a ramp.
The efficiency of the ramp is 25%. This is calculated by taking the ratio of output work to input work, which in this case is 24 J / 96 J = 0.25, or 25%.
No, it makes work easier at the expense of more work. Climbing stairs can be done faster than climbing a ramp, but climbing the ramp is easier, since it is less work over a longer time.
The work done is equal to the change in potential energy. If the ramp has a height of h meters, the work done is mgh Joules, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the ramp.
yes u need a metal coping for a mini ramp then it wouldn't work....good luck.
False. ApEx C;
No, rolling a cart up a ramp is an example of doing positive work, as energy is being transferred to the cart to lift it against gravity. Negative work would be done if the cart were rolling down the ramp, as energy would be lost against gravity.
That means the ramp rises 1 inch for every foot traveled. So, if you have a ramp that is 8 feet long it will have 8 inches of rise. If you have 12 inches of rise, then your ramp has to be 12 feet long.
It takes more work to lift the box because lifting against gravity requires more force than pushing along a ramp.
