Force necessary to change the momentum of an object depends on the time rate at which momentum is changed”. Comment with an example
Answers
Answer:
Explanation:
Momentum measures the 'motion content' of an object, and is based on the product of an object's mass and velocity. Momentum doubles, for example, when velocity doubles. Similarly, if two objects are moving with the same velocity, one with twice the mass of the other also has twice the momentum.
Force, on the other hand, is the push or pull that is applied to an object to CHANGE its momentum. Newton's second law of motion defines force as the product of mass times ACCELERATION (vs. velocity). Since acceleration is the change in velocity divided by time, you can connect the two concepts with the following relationship:
force = mass x (velocity / time) = (mass x velocity) / time = momentum / time
Multiplying both sides of this equation by time:
force x time = momentum
To answer your original question, then, the difference between force and momentum is time. Knowing the amount of force and the length of time that force is applied to an object will tell you the resulting change in its momentum.
