Answer:
a. 0.98 J
b. -0.98 J
c. 306.25 J/m²
Explanation:
(a)
(b)
The increase in gravitational potential energy = decrease in elastic potential energy
Elastic potential energy = -0.980 J
(c) The spring constant can be calculated as follows:
The compass magnet aligns itself with the earths magnetic field.
Answer:
Potential energy is stored energy that is stationary. Kinetic energy is energy in motion
Explanation:
Examples:
A car moving forward down a hill is kinetic energy
A car about to go down a hill after reaching the top is potential energy.

The force of gravity increases with an increase in the mass of objects. . . . A large, massive dog weighs more than a small dog.
Acceleration due to gravity is independent of the mass of objects. . . . Two falling inflated balls of different masses land at the same time.
Air resistance increases with an increase in the surface area of objects. . . . A crumpled ball of paper falls faster than a sheet of paper of the same mass.
