An object falls freely from rest on a planet where the acceleration due to gravity is
16 m/s2.
After 46s what will be its speed?

What are the theoretical properties of a gas at a temperature of 0 kelvin?

How to tell if two objects are in thermal equilibrium 1.the objects have the same temperature 2.the objects are the same size 3.the objects are touching each other 4.the objects temperatures are changing

Which body is in equilibrium? (1) a satellite orbiting earth in a circular orbit (2) a ball falling freely toward the surface of earth (3) a car moving with a constant speed along a straight, level road (4) a projectile at the highest point in its trajectory
