## What happens to kinetic energy of an object if its mass and velocity were doubled?

The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity.

This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with equal mass and twice the speed will have quadruple the kinetic energy..

## Does mass affect final velocity?

Explanation: When an object is dropped from a tower, mass does not affect final velocity or time.

## What happens to kinetic energy when velocity is tripled?

Answer: as we know K.E=1/2mv^2 from this eqn we get K.E is directly proportional to square of velocity of body so, if we triple the velocity of body the K.E will become nine times of the initial K.E.I hope you got it. Answer: … The Kinetic Energy is increased by a factor of 9 if the velocity is tripled.

## When the mass and velocity are doubled the kinetic energy will?

Kinetic energy is directly proportional to the squared of the velocity. This means that when momentum is doubled, mass remaining constant, velocity is doubled, as a result now kinetic energy becomes four times greater than the original value.

## Does increasing mass increase velocity?

Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.

## How does kinetic energy change when velocity is doubled?

If the velocity is doubled its kinetic energy is multiplied by four times. And there is no relationship between the velocity and potential energy. So, if the velocity is doubled, momentum also doubles.

## What will be the kinetic energy of a body if its mass is doubled?

Answer: The kinetic energy of the object is directly proportional to the mass, therefore on doubling the mass kinetic energy will also become double.

## Why does kinetic energy increase with velocity?

Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity.

## Does mass decrease as velocity increases?

Lesser mass provides lower resistance toward the motion of the object. If we assume kinetic energy to be constant, then velocity will be inversely proportional to the square root of mass. So as mass decreases, velocity will increase accordingly.

## What are the two factors that affects the kinetic energy of a moving object?

1. Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed.

## What is the relationship between force mass and acceleration?

It states that the rate of change of velocity of an object is directly proportional to the force applied and takes place in the direction of the force. It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.

## Do heavier objects fall faster?

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance.

## What happens if the mass is doubled?

If the net force on an object is doubled, its acceleration will double If the mass of an object is doubled, the acceleration will be halved .

## 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.

## What happens to acceleration when mass is increased?

If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.

## Why 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 will be the kinetic energy of a body when its mass is 4 times and velocity is doubled?

1 Answer. Kinetic energy of a body depends on its mass and its speed. Hence, ,kinetic energy will become 4 times the original kinetic energy if the speed is doubled.
