Question:
Suppose, a ball of mass M is thrown upwards from a point A and it reaches up to the highest point B and returns back to point A, which one among the following is correct?
Suppose, a ball of mass M is thrown upwards from a point A and it reaches up to the highest point B and returns back to point A, which one among the following is correct?
Options:
- Kinetic Energy at A = Potential Energy at B
- Kinetic Energy at A = Potential Energy at A
- Kinetic Energy at B = Potential Energy at B
- Kinetic Energy at B = Kinetic Energy at A
- Kinetic Energy at A = Potential Energy at B
- Kinetic Energy at A = Potential Energy at A
- Kinetic Energy at B = Potential Energy at B
- Kinetic Energy at B = Kinetic Energy at A
Correct Answer: Kinetic Energy at A = Potential Energy at B
Explanation:
To throw an object upward we need to give it some kinetic energy. As per conservation of energy, kinetic energy of object transfers into potential energy, as it rises upwards. At highest point entire kinetic energy gets converted into potential energy. i.e., KE_A = PE_B.
