## What factors affect kinetic energy?

Answer.

Answer: There are two factors that affect how much kinetic energy a moving object will have: mass and speed..

## What type of energy did the balls have just before they were released?

tational potential energy. As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy. The kinetic energy of an object is the energy it possesses due to its motion.

## What is the difference between kinetic and potential energy?

Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts. … On the other hand, kinetic energy is the energy of an object or a system’s particles in motion.

## How much potential energy does the ball have now?

How much potential energy does the ball have now? 1.96 J E.

## What happens to kinetic energy when an object slows down?

A moving object can slow down for different reasons. One is because of friction and another one would be because it slows down, if you throw it up into the air for instance. Both objects are slowing down and therefore their kinetic energy decreases. … So, the kinetic energy will increase again.

## What types of energy are both potential and kinetic?

Sound is made up of vibrations (put your hand on a stereo speaker), thermal energy consists of moving molecules in air or in an object, and mechanical energy is the combination of kinetic and potential energy of a moving object.

## Is dropping a ball kinetic or potential energy?

Lifting a ball into the air before dropping it gives it a type of energy called ‘potential energy’ – which means the ball has the potential to do some work. When you drop the ball, it gains ‘kinetic’ energy (the energy of motion) and loses its potential energy.

## Can an object have both kinetic and potential energy at the same time?

Potential energy is the energy stored in an object due to its position. … Objects can have both kinetic energy and potential energy at the same time. An object can be moving (have kinetic energy) and be elevated above the ground at the same time (and also have potential energy).

## How do you know if an object has potential energy?

To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

## What happens to potential and kinetic energy when an object falls?

As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy. Another important concept is work. … In fact, the potential energy plus the kinetic energy due to the force is constant!

## What is the potential energy and kinetic energy when you release the ball?

When you release the ball, it begins to fall down the track acquiring a speed, v. The ball’s potential energy (PE) is being converted into an equal amount of kinetic energy (KE)! At the bottom of the loop, all of the ball’s energy is now kinetic energy.

## What happens to kinetic energy when it hits something?

When the object hits the ground, the kinetic energy has to go somewhere, because energy isn’t created or destroyed, only transferred. If the collision is elastic, meaning the object can bounce, much of the energy goes into making it bounce up again.

## What Ball has the most potential energy?

Ball DWhy? Ball D has the greatest potential energy because it has the greatest height from the ground. GPE = mgh, increasing the h increases the GPE.

## How does speed affect kinetic energy?

It turns out that an object’s kinetic energy increases as the square of its speed. A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph. Thus a modest increase in speed can cause a large increase in kinetic energy.

## Why does the potential energy decrease as the ball falls?

Answer: As gravity continues to pull the cannon ball toward the earth, the ball will fall downwards, causing its height to decrease and its speed to increase. The ball’s potential energy decreases and its kinetic energy increases.

## What happens to the potential energy of the ball as it is raised?

As the ball rises, its gravitational potential energy is increasing and its kinetic energy is decreasing. … When the ball returns to its original height, its kinetic energy will be the same as when it started upward. When work is done on an object, the work may be converted into either kinetic or potential energy.

## Why does potential energy increase with height?

Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy.

## Does potential energy increase with temperature?

Yes, potential energy increases with increasing temperature for at least the following three reasons: At a higher temperature, more atoms/molecules are in excited electronic states. Higher electronic states correspond to greater potential energy. Potential Energy is -2 times Kinetic Energy.

## Does kinetic energy increase with height?

As the height increases, there is an increase in the gravitational potential energy P and a decrease in the kinetic energy K. The kinetic energy K is inversely proportional to the height of the object.

## What happens to kinetic energy when speed is doubled?

The kinetic energy is proportional to the square of the speed, so doubling the speed increases the kinetic energy by a factor of 4.
