## 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.

## When mass and velocity are doubled then kinetic energy will be?

Thus Kinetic energy is directly proportional to mass and velocity. 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.

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

Kinetic energy is proportional to squared speed. Doubling the speed makes an object’s kinetic energy four times larger.

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

Kinetic Energy is defined by states of motion. Therefore, when the velocity is 1/3 of the initial velocity then the Kinetic Energy is 1/9 of the Kinetic Energy with initial velocity.

## How is the kinetic energy of a moving car affected if its mass is doubled its velocity?

Hence, kinetic energy is doubled.

## 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.

## How does kinetic energy of an object change if a its mass is doubled and b its speed is doubled?

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.

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

Hence, kinetic energy of body is doubled.

## What is another name for movement energy?

Kinetic energy is the energy of motion, observable as the movement of an object or subatomic particle. Every moving object and particle have kinetic energy.

## What’s the formula for 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 relationship between velocity and kinetic energy?

Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples.

## Can kinetic energy be zero?

Since kinetic energy is based on motion, it is always a positive value. If it is not in motion, the kinetic energy of that object is zero. Kinetic energy can never be a negative value. Kinetic energy can be quantified as one half of the mass times the velocity squared (KE = 1/2*m*v²).

## What is 1G of force equal to?

1G is the acceleration we feel due to the force of gravity. It’s what keeps our feet firmly planted on the ground. Gravity is measured in metres per second squared, or m/s2. On Earth, the acceleration of gravity generally has a value of 9.806 m/s2 or 32.1740 f/s2.

## Is velocity positive or negative?

Velocity includes both speed and direction, thus velocity can be either positive or negative while speed can only be positive. Another way to say this is that speed is the absolute value of velocity.

## 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.

## How is the kinetic energy of a moving car affected if its velocity is reduced to half of its initial velocity?

Kinetic energy is directly proportional to velocity squared (K.E. = 12mv2). So, if velocity is halved, then kinetic energy becomes one fourth.
