Is it true that a car sitting at the bottom of the ramp has potential energy?
It depends on where the zero potential energy level is taken. If it is the ground, and the car is at the bottom of a ramp ON A TABLE, then it will have Ep. If the bottom of the ramp was taken as the zero Ep level, then it will have zero Ep.
Does a roller coaster car have potential energy?
It depends on where the zero potential energy level is taken. If it is the ground, and the car is at the bottom of a ramp ON A TABLE, then it will have Ep. If the bottom of the ramp was taken as the zero Ep level, then it will have zero Ep.
What is the relationship between the length of a ramp and the speed at the bottom?
The Object moving down the Ramp will have its POTENTIAL Energy (Speed=0) at the top of the Ramp changed to Kinetic Energy as it travels DOWN the Ramp. For any given INCLINE the LENGTH of the Ramp will dictate its HEIGHT. The higher the top of the ramp, the greater the Potential Energy to be Converted into Kinetic Energy. The Formula for K.E. is : K.E. = 1/2 Mass x Velocity2 (the 2 means Squared) So as the Potential Energy increases so does the Kinetic Energy. while the Mass is a Constant. Therefore the Velocity MUST increase as well to balance the K.E. equation.
How does friction affect the distance traveled by a toy car after rolling down a ramp?
at the top of the ramp the toy has a certain amount of potential energy. The amount of this energy depends on the height of the ramp and the weight of the toy. (The toy's weight is dependent on its mass and the force of gravity.) As the toy rolls down the ramp this potential energy is converted to two other types of energy: Kinetic energy and heat energy. The amount of heat energy depends on friction and air resistance. The lower the total resistance the more kinetic energy, and the more speed, the toy has at the bottom of the ramp.
Does height effect potentail energy?
yes height effects potentail energy because if you have a meter stick and a ramp at 50 centemeters with a block at the bottom then roll a ball down the ramp the block at the bottom will go pretty long but if you put the ramp higher the block will go longer
What device can change kinetic energy into potential energy?
Any ramp can.
What is the energy conversion when a marble is released from a ramp?
Potential Energy changes to Kinetic Energy.
What types of energy does a car gain when moving down a ramp?
i guess it potentail energy to kinetic energy
The ball rolling down an incline has its maximum potential energy at what point?
At the top, since potential energy is referred to an objects location, the highest the object the highest its potential energy.
Does a toy car sitting at the bottom of a ramp have potential energy?
No it doesn't. We use incline with the formula Wp=Wk where the potential energy at the top is max and kinethic energy iz 0. As the ball rolls down, the Wp(potential e.) iz getting smaller and Wk(kinethic e.) is getting bigger. on the bottom just before it hits the ground, all of the Wp is turned into Wk.. here we can use the formula m x g x h = 1/2 x m x v^2 and you can cross out the mass and get v^2 = 2 x g x h and you can calculate either the height of the incline or the top speed of the ball. If the ball just sits at the bottom it doesnt have any Wp.
What type of energy does a cart have before it starts to roll down a ramp?
It has Potential energy.
Why does a ball roll faster down a steep ramp than down a shallow ramp?
Potential Energy of the ball on the shallow ramp and the ball on the steep ramps are different: PE = mass x gravity x height. This potential energy is converted to Kinetic energy or motion energy. KE = 1/2mv^2. If there is more potential energy to convert to Kinetic energy then it will result in increased speed.
