Physics Question on momentum
An object is thrown vertically upwards. At its maximum height, which of the following quantity becomes zero?
A
Momentum
B
Potential Energy
C
Acceleration
D
Force
Answer
Momentum
Explanation
Solution
At topmost position, v = 0 ⇒ momentum = 0
The momentum of an object is given by the product of its mass and velocity. At the maximum height, the velocity becomes zero (momentarily), and if the mass remains constant, the momentum will indeed become zero at that point.
Therefore, in the context of the object thrown vertically upwards, the correct option is (A): Momentum.
