Which has greater kinetic energy a car traveling at 30 km HR or a car of half the mass traveling at 60 km HR?

Which has greater kinetic energy a car traveling at 30 km HR or a car of half the mass traveling at 60 km HR?

Which has greater kinetic energy, a car traveling at 30 km/h or a half-as-massive car traveling at 60 km/h? The car traveling at 60 km/h has more kinetic energy.

When a car is braked to a stop its kinetic?

When applying brakes to a car, kinetic energy is converted to heat and then dissipated into the environment via both radiation and convection. But, momentum is transferred to the earth. The act of breaking the car actually applies a spin to the earth in the forward direction of the car’s travel.

For which position above does the ball on the end of the string have the greatest gravitational potential energy?

For which position above does the ball on the end of the string have the greatest gravitational potential energy? The height is greatest at position A. 11.

Which has a greater kinetic energy a car traveling?

The formula for kinetic energy is one half the mass times velocity squared. Which means that if you double the velocity, the kinetic energy quadruples. Therefore, the lighter car travelling at twice the speed has greater kinetic energy. The car with half the mass has greater kinetic energy.

Which has more kinetic energy a car traveling at 30 km/h or a car with twice the mass traveling at 15 km h?

Keep this in mind: Kinetic energy is affected by speed. Potential energy is affected by elevation. Since both have the same mass, the car moving at twice the speed (i.e. the 30 km/h car) has 4 times the kinetic energy as the other car (the 15 km/h car).

What is kinetic en?

Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

When brake are applied on a moving vehicle the kinetic energy is converted to?

Background. Most brakes commonly use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat, though other methods of energy conversion may be employed.

What is the energy of a moving object called?

Kinetic energy
Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

Which has greatest kinetic energy?

First, heavier objects that are moving have more kinetic energy than lighter ones: a bowling ball traveling 10 m/s (a very fast sprint) carries a lot more kinetic energy than a golf ball traveling at the same speed.

Which has a greater kinetic energy a car traveling at 30 m/s or a car of half the mass traveling at 60 m s?

Which has greater kinetic energy, a car traveling at 30 km/h or a half-as-massive car traveling at 60 km/h? Both have the same kinetic energy. You just studied 74 terms!

What has a lot of kinetic energy?

1. An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity. 2. A baseball thrown by a pitcher, although having a small mass, can have a large amount of kinetic energy due to its fast velocity.
