Weather differs from climate in that weather can change on a daily basis and is not considered a description of year-to-year conditions of temperature and precipitation.

A 40 kg dog is sitting on top of a hill side and has a potential energy force of 1568 J. What is the height of the hillside?

A car is moving with a velocity (3.0 m/s) € x ˆ + (1.0 m/s) € y ˆ and 3.0 seconds later its velocity is (6.0 m/s) € x ˆ - (3.0 m/s) € y ˆ. What is the direction of the average acceleration of the car?

When water vapor condenses on the inside of a window, the window becomes

Try this out. Use a calculator! We can use the formula KE=0.5m*V^2. To find the kinetic energy (KE) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s. (Multiply 0.5 x the mass x velocity squared.
