In order to change the momentum of an objective there must be:
- A
A force applied
- B
A change in time
- C
A change in distance
- D
A change in temperature
Fact.
According to Newton's second law of motion, force is the rate of change of momentum i.e: F = d p/dt
And hence a force acting for a given amount of time will change an object's momentum. Put another way, an unbalanced force always accelerates an object - either speeding it up or slowing it down.
