## What is the kinetic energy of a body of mass 20 kg is moving with a velocity 5m s?

The correct answer is 250 J. Given, mass (m) = 20 kg, velocity (v) = 5 ms-1. So, the kinetic energy of the object is (½)∗20∗52 = 250 J.

## How does the kinetic energy of a body affected if its mass is doubled and velocity is reduced to one third?

Expert-Verified Answer (1)Its mass is double-The kinetic energy becomes two times. (2)Its velocity is reduced to one-third of the initial velocity-The kinetic energy reduces to one-ninth of its initial value.

## What is the effect on the kinetic energy of a moving car if its mass is doubled?

Kinetic energy is equal to half of the product mass and velocity. SI unit is joules. 1) If mass doubled then kinetic energy also gets doubled.

## What is the kinetic energy of a body of mass 15 kg?

The kinetic energy of a body of mass 15 kg is 30j.

## What is the kinetic energy of an object of mass m moving with velocity of 5m s?

The kinetic energy of an object of mass, m moving with a velocity of 5ms−1 is 25 J.

## How is the kinetic energy of a moving cart affected if its velocity is reduced to 1 3 of its initial velocity?

Reducing v to 1/3 v reduces KE by (1/3)^2 = 1/9.

## How is the kinetic energy of a moving body affected if its velocity is reduced to one third of the initial velocity?

So, K.E. becomes 19th of its initial K.E.

## What happened to the kinetic energy when mass of the body is doubled by velocity is reduced to half?

Therefore, Kinetic Energy is reduced to half, when mass is doubled, and velocity is halved. Similarly, when you increase mass to 3 times and decrease the velocity by a factor of 3, the KINETIC ENERGY changes to 1/3^rd.

## What happens to kinetic energy when mass and velocity are doubled?

Since mass is directly proportional to K.E and K.E is directly proportional to the square of velocity the kinetic energy becomes eight times.

## When the mass of an object doubles what happens to the objects kinetic energy?

If mass doubles, kinetic energy doubles as well, but if velocity doubles, kinetic energy increases by a factor of four. That’s because velocity is squared in the equation.

## What happens to the kinetic energy when the mass of a moving object increases?

The more mass an object has, the more kinetic energy it has.

## What is the kinetic of an object of mass 15 kg is moving with a uniform velocity of 4m s?

So kinetic energy of given object = 120 J.

## What is the formula for mass in kinetic energy?

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 is the kinetic energy of a body of 2 kg when a force of 10 Newton acts on it for 3 second?

Solution: A force of 10 N acts on a body of 2 kg at rest for 3 seconds. The kinetic energy acquired by the body in 3 seconds will be 225 J.

## What would be the kinetic energy of an object of mass 20 kg is moving with uniform velocity 5 ms1?

The Kinetic Energy of the object will be 250 J. So option 4 is correct.

## What is the kinetic energy of a body of mass moving with velocity?

The kinetic energy possessed by a body of mass m moving with a velocity v is equal to 1/2 mv2 , provided.

## What is the kinetic energy of a body of mass 2 kg moving with a velocity of 0.1 m?

The correct answer is: 0.01 J With an increase in its height the potential energy increases.

## What is the kinetic energy of a body of mass 2 kg moving with a velocity of 0.1 m as 1?

- Answer:
- Explanation:
- 1/2 mv²
- K.E = 1/2 mv²
- K.E = 0.01 J.
- Hence, the kinetic energy of a body is 0.01 Joule.
