Question

a ball is thrown vertically upwards at the highest point of the vertical path the ball will have


choose the correct answer
the greatest kinectic energy

the greatest potential energy

equal kinetic and potenial energies

a potential energy that is smaller than its kinectic energy ​

Answer 1

Answer:

the greatest potential energy

Answer 2

The greatest Potential Energy.

• Let's assume that a ball is thrown vertically upwards with an initial velocity of u. Gravitational acceleration is g downwards.

• So, the maximum height reached is u²/2g.

• At the max height, the ball is momentarily at rest. So, v = 0. Hence, its Kinetic Energy at that position will be zero.

• However, it will have max POTENTIAL ENERGY by the virtue of its height (i.e. PE = m×g×h)

• Similarly at ground, the ball will have maximum KE and minimum PE, because velocity $\neq$ 0 , but h = 0.
