# What Is The Kinetic Energy Of A 45 Kg Object Moving At 13 M S?

## What is the kinetic energy of a bike with a mass of 16 kg traveling at 4 m s?

So, we got 128 J of kinetic energy, i.e.

the object’s kinetic energy is 128 joules..

## What are two examples of kinetic and potential energy?

What Are Examples of Potential and Kinetic Energy?1) Planets. The movement of planets around the sun and other stars in the galaxy is kinetic energy at work. … 2) Rubber Bands. Rubber bands can be classified as both potential and kinetic energy, depending on the state of the band. … 3) Rivers. … 4) Specific Variations.

## What happens when kinetic energy decreases?

Kinetic energy is the energy of movement or change. … The sum of an object’s potential and kinetic energies is called the object’s mechanical energy. 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.

## What is the kinetic energy of a 1200 kg object that is moving with a speed of 24 ms?

KINETIC ENERGY=345600Joules.

## What is the kinetic energy of a 1500 kg object moving at a velocity of 10 m s?

Square the 10 m/s! Multiply! Divide! KE = 75,000 Newton-meters or Joules!

## 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.

## What is the equation for kinetic energy of a moving object?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

## 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 are two ways to increase kinetic energy?

If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. The word “kinetic” comes from the Greek word “kinesis” which means motion. Kinetic energy can be passed from one object to another in the form of a collision.

## What are examples of kinetic energy at home?

Here are some Kinetic Energy Examples:when you are walking or running your body is exhibiting kinetic energy.A bicycle or skateboard in motion possesses kinetic energy.Running water has kinetic energy and it is used to run water mills.More items…•Dec 19, 2020

## How do you find the maximum kinetic energy?

The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe = hf − BE, where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.

## How do I calculate kinetic energy?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

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

The primary relationship between the two is their ability to transform into each other. In other words, potential energy transforms into kinetic energy, and kinetic energy converts into potential energy, and then back again.

## Is heat kinetic or potential energy?

Heat energy is actually made up partly of kinetic energy and partly of potential energy. In a solid, for example, it’s the kinetic energy and potential energies of the atoms as they wiggle around.

## Why is there a 1/2 in the kinetic energy formula?

the formula for kinetic energy is the integral of momentum (Force)(Speed), so when you take the integral you have to add the 1/2 to ensure that the equation is correct. … *From the force equation () we know that acceleration is equal to force divided by mass.

## What is the kinetic energy of an object?

Kinetic energy is the energy an object has because of its motion. … After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed. The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.
