If you drop a softball from just above your knee, the kinetic energy of the ball just before it hits the ground is about 1 joule

Your friend won the race that you were both running. Instead of being gracious, your friend made fun of you for losing, and now you don't want to run anymore.

A one-piece cylinder has a core section protruding from the larger drum and is free to rotate around its central axis. A rope wrapped around the drum of radius 1.39 m exerts a force of 3.34 N to the right on the cylinder.

The emission spectra you obtained from a star show a hydrogen spectrum that is shifted toward the blue end of the electromagnetic spectrum compared to the hydrogen spectrum you obtained from the lab.

Which theory proposes that the moon was a passing asteroid pulled into orbit by Earth's gravity?

A cylinder with a piston contains 0.8 kg of water at 100 degrees C. What is the change in internal energy of the water when it is converted to steam at 100 degrees C at a constant pressure of 1 atm?

Determine the total mechanical energy of a 250 g baseball if it has a velocity of 30 m/s when it leaves the pitcher's hand 1.2m above the ground.

When distances were carefully measured from Earth to globular clusters above and below the Milky Way plane (where our view of them is not obscured by interstellar dust and gas), their distribution was found to be

Imagine you transfer heat into a gas. This heat splits up in two different ways: Additional thermal energy making the gas hotter and "fuel" for the gas to do work. Let's suppose, 64% of the transferred heat transforms into thermal energy.

How much heat is absorbed by a 61g iron skillet when its temperature rises from 5oC to 29oC?

Explain the relationship between motion and frame of reference.
