KE = 1/2mV2
KE = 1/2(30 kg)( 5m/s)2
= 750 joules of kinetic energy
===================
Kinetic Energy = (1/2)(m)(v2) where m=mass of object, v=velocity of object
Substituting values into the equation.
Kinetic Energy = (1/2)(45)(10)2 = 2250 J
2,250 joules
KE=(0.5)(m)(v)^2 KE=225J
mechanical energy
potential when it starts ,then kinetic when it starts to move ,then lights if the roller coaster has lights ,then heat because of the friction between the tracks of the roller coaster and the actual car and it also has heat because every thing has heat energy no matter what
If it is a rollercoaster that has a first drop hill, the roller coaster has the greatest kinetic energy at the bottom of that drop. If it is magnetically launched, the kinetic energy is probably greatest immediately after the launch. However, there are cases where these statements may not be true. (i.e. a drop right after a magnetic launch)The energy is the greatest at the bottom of a drop, before some is translated back into potential energy as the car climbs the next rise.
At the top of the hill the roller coaster car has potential energy and no kinetic energy but as the car goes down the hill the kinetic energy increases and the potential energy decreases. This pattern continues at every top and every bottom of each hill. A roller coaster track is built with each hill getting a little smaller each time as the car looses energy over each hill due to air resistance and friction. As the car travels along the tracks some of the kinetic energy is converted to thermal energy because of the friction.
KE=(0.5)(m)(v)^2 KE=225J
kinetic_energy = ½mv² = ½ × 45 kg × (10 m/s)² = 2250 Joules.
The roller coaster increases kinetic energy when its velocity is increasing.
If you are crazy enough to try, I don't see why not :)
The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path.
Kinetic energy comes from movement. If the roller coaster is moving at the top of the hill, it has kinetic energy. if the rollercoaster isn't moving then it has potential energy.
If you are talking about the one in Massachusetts, in the Whitman area then yes. They are black and orange. Just saying.
Potential energy is used when going up hill on a roller coaster. When it starts gong down the potential energy is converted to kinetic energy.
