What happens when you add heat to a substance? (think of the kinetic theory of matter)

Can a car that has only been traveling at different speeds in a straight line east have accelerated north?

Example of experiment

1 - A 30 gram bullet travels at 300 m/s. How much kinetic energy does it have?

This is the rate of flow electricity

You took a running leap off a high diving platform. You were running at 3.1 m/s and hit the water 2.4 seconds later.

How are mass and weight different? a. Mass is the space an object takes up and weight is the effect of gravity on mass. b. Mass is the amount of matter and weight is the effect of gravity on mass. c.
