Why does the height of a ramp affect a toy cars speed going down it?
Because a higher ramp gives more potential energy than a shorter one.
How do you think the potential energy will change if you change the length of the ramp?
Gravitational potential energy depends on the difference of height. If the length of the ramp is changed, but the endpoints have the same difference in height, there won't be any change in gravitational potential energy. If, on the other hand, the change is done in a way that the height does change, then gravitational potential energy will also change.
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.
Which type of energy is the person using to move the wheelchair up the ramp?
Mechanical force pushes the wheelchair up the ramp. The total weight multiplied by the height gain is the gain in potential energy. The energy needed is that plus a little extra to allow for friction. The potential energy in joules is the weight in Newtons times the height in metres.
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.
How does the increasing the height of a ramp affect how far a ball rolls down ramp?
how does increasing the height of a ramp affect how far a ball rolls down the ramp
What is the Kinetic Energy of the trolley at the top of the ramp if a trolley of mass is 25Kg and is released from the top of a ramp which stands at a height of 3m?
What is the Kinetic Energy of the trolley at the top of the ramp if a trolley of mass is 25Kg and is released from the top of a ramp which stands at a height of 3m? Mass = 25 Kg Height = 3 m This is an energy problem. At the top of the ramp, the trolley is at rest and 3m above the base line. Potential Energy = Weight * height Weight = mass * acceleration due to gravity Acceleration due to gravity = 9.8m/s^2 Potential Energy = 25 kg * 9.8m/s^2 * 3 m Potential Energy = 735 Joules When the trolley reaches the bottom of the ramp, all the potential energy has been converted to Kinetic energy. Potential Energy = 735 Joules = Kinetic energy Kinetic energy = ½ * mass * velocity^2 Kinetic energy = ½ * 25 * V^2 = 735 multiply 735 by 2 and divide by 25 V^2 = 58.8 V = 7.67 m/s
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.
Which has more potential energy a 10 kg box rolled on a 5 meter long ramp up to ledge or a 10 kg box rolled up a 20 meter long ramp?
The potential energy that the box gained only depends on how high it was raised, not on how it got there. If both boxes started at the same height and ended at the same height, then they both gained the same amount of potential energy.
Does the height of a ramp affect a toy car's speed 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
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
Does the height of a ramp affect the speed of a marble?
Yes.The higher the ramp the faster.
