## Inelastic Collision Example Problem – Physics Homework HelpRecently updated !

A collision is considered an inelastic collision when kinetic energy is lost during the collision. This inelastic collision example problem will show how to find the final velocity of a system and the amount of energy lost from the collision. Inelastic Collision Example Problem Question: A 3000 kg truck travelling […]

## Elastic Collision Example Problem – Physics Example Problems

Elastic collisions are collisions between objects where both momentum and kinetic energy are conserved. This elastic collision example problem will show how to find the final velocities of two bodies after an elastic collision. This illustration shows a generic elastic collision between two masses A and B. The variables involved […]

## Impulse and Momentum – Physics Example Problem

Impulse and momentum are physical concepts that are easily seen from Newton’s Laws of Motion. Start with this equation of motion for constant acceleration. v = v0 + at where v = velocity v0 = initial velocity a = acceleration t = time If you rearrange the equation, you get […]

## Moving Rulers Are Shorter – Length Contraction Example Problem

Relativity tells us moving objects will have different lengths in the direction of motion, depending on the frame of reference of the observer. This is known as length contraction. This type of problem can be reduced to two different frames of reference. One is the frame of reference where a […]

## Conservation of Momentum Example Problem

Momentum is a measurement of inertia in motion. When a mass has velocity, it has momentum. Momentum is calculated by the equation momentum = mass x velocity momentum = mv This conservation of momentum example problem illustrates the principle of conservation of momentum after a collision between two objects. Problem: […]
