## What is the movement of an object of mass m moving with a velocity v?

The momentum, p of an object is defined as the product of its mass, m and velocity, V. Momentum = Mass x Velocity. That is, p = mv.

## What will be the velocity of mass m after elastic collision?

When target is very light and at rest then after head on elastic collision it moves with double speed of projectile i.e. the velocity of body of mass m will be 2v.

## What is the kinetic energy of mass m is moving with speed v?

Kinetic energy of a ball of mass and moving with speed is. E . = 1 / 2 M v 2.

## What is the formula for velocity vs mass?

Mass is measured in (kg), and velocity is measured in meters per second (m/s). The SI unit for momentum is kg • m/s. You can rearrange the equation to calculate velocity if you know momentum and mass, Velocity = Momentum/Mass, or to calculate mass if you know momentum and velocity, Mass = Momentum/Velocity.

## What happens when two objects of equal mass and velocity collide?

When two objects with the same mass collide, Newton’s laws tell us that they will accelerate the same amount but in opposite directions. Recall that force, velocity, and acceleration have both magnitude and direction. We use positive and negative signs to indicate the direction of each of these quantities.

## What is the formula for velocity after collision?

From the conservation of momentum, the formula during a collision is given by: m1v1 + m2v2 = m1v’1 + m2v’2. If the collision is perfectly inelastic, the final velocity of the system is determined using v’ = (m1v1 + m2v2)/m1 + m2.

## What is the final velocity after elastic collision?

Question 1: What does the final and initial velocity mentioned in the elastic collision formula mean? Answer: The initial velocity of an object is the velocity it has before colliding with another item, whereas the final velocity is the velocity it has after colliding with another object.

## Is V velocity or speed in the kinetic energy formula?

This equation states that the kinetic energy (Ek) is equal to the integral of the dot product of the momentum (p) of a body and the infinitesimal change of the velocity (v) of the body.

## In which type of collision there is maximum loss of energy?

In physics, an inelastic collision occurs when some amount of kinetic energy of a colliding object/system is lost. The colliding particles stick together, and the maximum amount of kinetic energy is lost in a perfectly inelastic collision.

## What is the relationship between mass velocity and KE?

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 product of the mass of a moving object and its velocity?

The product of mass and velocity is called momentum. The SI unit of momentum is kgms−1.

## What is mass of an object moving with velocity V according to Einstein’s theory of relativity?

According to Einstein’s theory of relativity, the mass m of a body moving with velocity v is m=m0√1−v2c2, where m0 is the initial mass and c is the speed of light.

## What is moving energy with mass and velocity?

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 an object of mass m moving with constant velocity v has a net force on it equal to?

Answer and Explanation: If the velocity is not changing then the acceleration is zero. Thus the net force on the object is zero. The answer is (d) 0.
