Answer:
coasting down hill on a bicycle
Explanation:
Coasting down the hill on a bicycle is a typical example of how kinetic energy is being transformed to potential energy in a system.
Kinetic energy is the energy due to the motion of a body, it can be derived using the expression below;
K.E = m v²
Potential energy is the energy due to the position of a body. It can be derived using;
P.E = mgh
m is the mass
v is the velocity
g is the acceleration due to gravity
h is the height
Now, at the top of the hill, the potential energy is at the maximum. As the bicycle coasts down the potential energy is converted to kinetic energy.
The Gravitational Force between given objects will be ~
We know that ~
where ~
- F = gravitational force
= mass of 1st object = 70 kg
= mass of 2nd object = 2000 kg
- G = gravitational constant =
- r = distance between the objects = 1 m
Let's calculate the force ~
