When the child is moving, he/she has kinetic energy. For just a brief second before they move the other way, the child is not moving, but they have gravitational potential energy.
The child may need a push from time to time because friction with the air causes loss of energy.
C. It transfer energy as heat to the surrounding air. This answer is incorrectly
100 meters divided by a speed of 12.5 meters a second equals 8 seconds.
Answer:
increases
Explanation:
it would have to work harder to get to two points together
90 F = 43 OR 0.9F = 0.43
(F = 43 / 90 OR 0.43 / 0.9 =) 0.48 N
upwards force = downwards force
(R =) 1.2 N
