See what temperature Fahrenheit and Kelvin are equal and see how to set up and solve the temperature conversion problem.

# Physics Example Problems

Potential energy is energy attributed to an object by virtue of its position. When the position is changed, the total energy remains unchanged but some potential energy gets converted into kinetic energy. The frictionless roller coaster is a classic potential and kinetic energy example problem. The roller coaster problem shows […]

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 wherev = velocityv0 = initial velocitya = accelerationt = time If you rearrange the equation, you get v – v0 = […]

## Impulse and Momentum – Physics Example Problem

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 […]

## Moving Clocks Run Slower – Time Dilation

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 […]
