Answer:As a pendulum swings, its potential energy converts to kinetic and back to potential. ... A swinging pendulum.
Explanation:During the course of a swing from left to right, potential energy is converted into kinetic energy and back.
Answer:
The force exerted by the ball on the bat has a magnitude of 100 N and its direction is exactly opposite to that of the force exerted by the bat on the ball.
Explanation:
Recall that Newton's third law tells us that : "For every action, there is an equal and opposite reaction."
Therefore if the bat acts on the ball with a force of 100 N, the ball acts on the bat with a similar magnitude of force (100 N) but direction opposite to the original force.
A set of stars will appear at a different angle to us at different times of the year because of the Earth's orbit around the sun. As it orbits around the sun, the parallax of the stars change.
C) it is chemical energy to thermal energy.
Force = mass * acceleration
20 = 4a
20/4 = a
5 m/s^2 = a
