# What will happen to kinetic energy of a body if its velocity becomes 4 times the original velocity?

## What will happen to kinetic energy of a body if its velocity becomes 4 times the original velocity?

m is the mass of the body, v is the speed of the body. Now, the speed is four times. So the kinetic energy becomes 16 times.

## Is the momentum of a car traveling south different from?

The momentum of a car traveling south is different from the momentum of an identical car traveling north at the same speed. Similar to the raindrop and the supertanker question, momentum is a measure that includes both the mass and the velocity of an object.

## When we increase the velocity of a car moving on a flat surface to four times its original speed its potential energy?

If we increase the velocity of a car moving on a flat surface to four times its original speed, its potential energy will not change.

## What are the units of momentum?

In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second.

## 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.

## When kinetic energy becomes 4 times?

Therefore, for the kinetic energy to increase by four times, the momentum should have to be doubled, i.e. the final momentum needs to be twice the initial momentum.

## What is the difference between a car moving at 60km h and a car moving at 60km h north?

When we say a car travels at 60 km/h, we are specifying its speed. When we say a car moves at 60 km/h to the north, we are specifying its velocity.

## Is direction of momentum same as velocity?

The symbol for momentum is p and SI units are either N sec or kg m/sec. The direction of the momentum is the same as that of the velocity. High mass objects can have low momentum when they have low velocities; low mass objects can have high momentum when they have high velocities.

## Is momentum the same as direction?

As a vector quantity, the momentum of an object is fully described by both magnitude and direction.

## Why is it called potential energy?

Any object that is lifted from its resting position has stored energy therefore it is called potential energy because it has a potential to do work when released.

## When a car’s velocity is doubled its momentum?

Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

## What does power equal to?

Power equals work divided by time. The unit for work is the joule, and time is measured in seconds. A joule-per-second is called a watt (or W), which is the unit for power.

## What happens with kinetic energy when velocity is 3 times?

For a threefold increase in speed, the kinetic energy will increase by a factor of nine.

## When the velocity of an object is increased 4 times then its kinetic energy will be?

If the velocity of an object is increased 4 times and the mass remains constant, the kinetic energy of the object will increase by a factor of 16. This is because the kinetic energy is a function of the square of the velocity. K.E=1/2*m*v^2. where m is the mass and v is the velocity.

## What happens to the kinetic energy of a body when its velocity becomes three times?

Hence, new kinetic energy becomes 9 times.

## What will be the kinetic energy when its velocity is doubled and mass is 4 times?

Hence, the kinetic energy will be 16 times the initial kinetic energy.
