## 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 […]

## Elastic Collision of Two Masses – It Can Be Shown Exercise

An elastic collision is a collision where total momentum and total kinetic energy is conserved. This illustration shows two objects A and B traveling towards each other. The mass of A is mA and the moving with velocity VAi. The second object has a mass of mB and velocity VBi. […]

## 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 Clocks Run Slower – Time Dilation

Special relativity theory introduced an interesting notion about time. Time does not pass at the same rate for moving frames of reference. Moving clocks run slower than clocks in a stationary frame of reference. This effect is known as time dilation. To calculate this time difference, a Lorentz transformation is […]
