Objects use more energy when increasing in speed or starting while objects use less energy while going at a steady pace.

How is energy conserved when a car is going down a hill with no brakes?

The engine doesn't have to use as much fuel when the car is traveling downhill.


When a moving car slows down it's kinetic energy decrease?

When a moving car slows down, its kinetic energy decreases because kinetic energy is directly related to an object's speed. As the car decelerates, its speed decreases, causing its kinetic energy to decrease as well. This energy is ultimately transferred into other forms, such as heat generated by the brakes.


Is the total energy of the car always conserved?

Basically, in physics, total energy is always conserved. Of course, it is possible for some of the energy from a car to go somewhere else.


How is energy conserved when a car runs out of gas and stops?

When the car has no gas, no energy is used and no energy is produced.


What part of a car slows it down?

"Brakes" make the whole car slow down.


What force slows car hitting the brakes?

Generally speaking for cars that have "disk brakes", friction slows the car. When the driver presses down on the brake pedal the brake calipers squeeze the brake pads against the brake rotor inside each car wheel causing the car to slow down by friction.


How is energy conserved when a car hits another car during an accident?

Most of the mechanical (or kinetic) energy is converted to heat.


When a car slows down at a traffic light it is?

converting kinetic energy into thermal energy through friction in the brakes, resulting in a decrease in speed.


When a car slows down is it accelerating?

Yes. Acceleration is any change in velocity. When a car slows down it is decelerating; think of deceleration as acceleration in the negative direction.


Why does a car slow down when you accelerate?

A car goes faster when you accelerate. It slows down when you brake.


What is a object that shows acceleration?

A car coasts up a hill. As it climbs it slows down. Which type of energy is the car losing as it goes up?

The car is losing kinetic energy as it climbs the hill. This kinetic energy is being transferred into potential energy due to the increasing height gained during the climb.
