If somebody throw a curve ball would that be kinetic energy or potential energy

Describe the relationship between volume, mass and density.

Walter Arfeuille of Belgium lifted a 281.5 kg load off the ground using his teeth. Suppose Arfeuille can hold just three times that mass on a 30.0° slope using the same force.

In this situation, the Biot-Savart Law tells us that the magnetic field at the center of the loop is proportional to the current in the loop multiplied by the length of wire used to make the loop.

The relationship between period and frequency is represented by the following equation: frequency = 1/period or period = 1/frequency true or false

How much gravitational potential energy does a 45.2 kg object have when it is 21.9m above the ground?

During a snowball fight two balls with masses of 0.4 kg and 0.6 kg, respectively, are thrown in such a manner that they meet head on and combine to form a single mass of 1 kg. the magnitude of intial velocity foreach is 15 m/s.
