A ball is dropped from a 150-m tall building. Neglecting air resistance, what will the speed of the ball be when it reaches the ground 5.5 second later?

If the electric flux through a closed surface is proportional to the enclosed charge, what is the gravitational flux proportional to?

Two charges, q1 and q2, are separated by a certain distance r. if the magnitudes of the charges are halved and their separation is halved, then what happens to the electrical force between these two charges?

A sled starts atop a hill at rest with 3,000 J of potential energy relative to the bottom of the hill. When the sled reaches the bottom of the hill it has 2,000 J of kinetic energy.

A bird sitting high in a tree is an example of an object with what type of energy

The height a ball bounces is less than the height of the previous bounce due to friction. The heights of the bounces form a geometric sequence. Suppose a ball is dropped from one meter and rebounds 95 % of the height of the previous bounce.
