Question

8. A particle is thrown upward with some kinetic energy. What happened to its kinetic energy at the highest point or height it reaches?

Answer 1

When a particle is thrown upward with some kinetic energy then, it's velocity starts decreasing. Due to continuously decrease in velocity, Kinetic Energy also starts decreasing.

We know that,

K.E. = 1/2 mv²

At the highest point, v = 0. So,

K.E. = 1/2 m (0)²

K.E. = 0

Therefore, Kinetic Energy is also zero.

At the highest point, Kinetic Energy becomes zero and Kinetic Energy converts into Potential Energy.

Answer 2

Answer:

When a particle is thrown upward with some kinetic energy then, it's velocity starts decreasing.

Explanation:

When a particle is thrown upward with some kinetic energy then, it's velocity starts decreasing. At the highest point, Kinetic Energy becomes zero and Kinetic Energy converts into Potential Energy.
