# What is the kinetic energy of an object that has a mass of 30 kilograms and moves with a velocity of 20 ms?

6,000 j

### What are objects that have kinetic energy?

Kinetic energy is 1/2 x mass x velocity squared. Therefore, any object that has both mass and velocity will have kinetic energy. Kinetic energy is 1/2 x mass x velocity squared. Therefore, any object that has both mass and velocity will have kinetic energy. Kinetic energy is 1/2 x mass x velocity squared. Therefore, any object that has both mass and velocity will have kinetic energy. Kinetic energy is 1/2 x mass x velocity squared…

### Can a single object have kinetic energy but no momentum?

No, an object cannot have kinetic energy and no momentum. Here's the reason: Kinetic energy is the energy an object derives from being in motion. If an object is moving, it has some non-zero velocity. Momentum is the product of mass (which the object will have) and velocity, which it must exhibit to have kinetic energy. That is why an object cannot have kinetic energy with no momentum.

### What happens to kinetic energy if the speed of an object increases?

The kinetic energy will increase. Kinetic energy is defined by K=one half mv2 where m is the mass of the object, and v is the velocity of the object. The greater the velocity, the greater the kinetic energy. Since the velocity is squared, increasing it will cause the kinetic energy to grow much faster than if you increased the mass.

### An object that has kinetic energy must have?

An object that has kinetic energy must have momentum, velocity, and speed. Momentum is mass times velocity. Kinetic energy is mass times velocity squared. Speed is distance divided by time. Kinetic energy is the energy of the object's motion. An object that has kinetic energy must have momentum because is the force or speed of movement. For example the ball gained momentum as it rolled down the hill. An object that has kinetic energy must…
