WORK IS A TRANSFER OF ENERGY Car moving= 80km/hFrictional Force=4500NDistance = 50mWork= “Does the energy of the car increase or decrease as a result of the braking action”?
increase
What happens to the potential energy of a car parked at the top of the hill if you double the mass of the car?
The potential energy will double too.
How can you increase gravitational potential energy for a car?
Drive up a hill.
What happens when you decrease the velocity of a car?
as you decrease the velocity of a car, you decrease the kinetic energy.
What happens to chemical energy when it is not used in a car?
it blows up
What happens to the thermal energy in a car?
The cooling system moves the heat (thermal energy) to the air.
What happens to the wasted thermal energy in a car?
The cooling system moves the heat (thermal energy) to the air.
When a car burns fuel which of following best describes what happens to the energy of the system?
Chemical energy is transformed to mechanical energy and some heat energy
Will pushing on a car always change the cars mechanical energy what must happen for the cars kinetic energy to increase?
I don't know
What happens to Kinetic energy of a move a moving car if you double the mass of the car?
It becomes less since the weight is doubled so it becomes harder for the energy to push it
What happens if you don't charge a car battery?
It will eventually run out of the stored electrical energy and will not power anything. You car will not start.
What must happen for a car's kinetic energy to increase?
K.E = 1/mv2, where m is mass in kg and v is speed in m/s. By pressing down on the gas pedal, the speed of the car will increase, which will increase its kinetic energy. Note: Even though the symbol v is used in the equation, it represents speed and not velocity (speed and direction). Kinetic energy is not a vector quantity.
