## What is the energy of a particle moving 5m per second?

The energy of a particle moving at 5 m/s is 125 J.

## What happens after a perfectly inelastic collision between two identical balls moving with the same speed?

After a perfectly inelastic collision between two identical balls moving with the same speed in different directions, the speed of the combined mass becomes half of their initial speed.

## What is the speed of a particle that travels 60 meters in 4 seconds?

Expert-Verified Answer Therefore, the speed of the object that travels 60 meters in 4 seconds is 15 meters per second.

## What is the kinetic energy of a 10 kg object moving at 5 ms?

The kinetic energy of the object is 125 J.

## What happens when 2 identical objects collide while moving at the same speed?

Both momentum and kinetic energy are conserved quantities in elastic collisions. Suppose two similar trolleys are traveling toward each other with equal speed. They collide, bouncing off each other with no loss in speed. This collision is perfectly elastic because no energy has been lost.

## What happens when 2 balls of different mass collide with the same force?

In a collision, there is a force on both objects that causes an acceleration of both objects. The forces are equal in magnitude and opposite in direction, yet the least massive object receives the greatest acceleration.

## What happens when 2 identical masses collide in an elastic collision?

Two objects that have equal masses head toward each other at equal speeds and then stick together. The two objects come to rest after sticking together, conserving momentum but not kinetic energy after they collide.

## What are the 3 formulas for velocity?

- v = u + at.
- v² = u² + 2as.
- s = ut + ½at²

## What is the SI unit of speed?

The SI unit of speed is the meter per second, abbreviated as m/s or ms-1.

## What is the SI unit of velocity?

The SI unit of velocity is metre per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimetres per second (cm/s).

## What is the formula for the energy of moving particles?

The kinetic energy of a particle is one-half the product of the particle’s mass m and the square of its speed v: K=12mv2. K = 1 2 m v 2 .

## What is the energy of a moving particle?

Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

## What is the total energy of a moving particle?

A particle of rest mass mo, moving with velocity v, has total energy En + K = ½moc^2 (1 + v^2 /c^2) = ½mvc^2 , where mv = mo(1 + v^2/c^2) is the impact mass. Content may be subject to copyright. energy E + K = ½mc(1 + v/c) = ½mc, where m = m(1 + v/c) is the “impact mass”.

## What is the energy of motion of a particle?

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. A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy at work.
