Explanation:
Such an object will gain no gravitational potential energy since it moves horizontally.
Gravitational potential energy is the energy possessed by two massive bodies at a distance from one another in the presence of gravity.
- In the horizontal direction, there is no sense of gravity as the body is not moving away or towards the center of the earth.
- Gravitational potential energy is expressed as;
E = mgh
m is the mass
g is the gravity
h is the height
Gravity component in the horizontal direction is 0
Whenever there is a change in velocity, either due to a change in speed or a change in direction, there will be non-zero acceleration. ... Acceleration is not constant if the net force is not constant.
