* Momentum: Momentum is the measure of an object's mass in motion. It's calculated by multiplying mass (m) and velocity (v): p = mv.
* Constant Mass: If the mass remains the same, any change in momentum must be due to a change in velocity.
* Acceleration: Acceleration is the rate of change of velocity. If velocity changes, the object is accelerating.
Therefore, a constant mass object with changing momentum signifies that the object is experiencing a change in its velocity, which means it is accelerating.
Here are some examples:
* A car speeding up: The car's mass stays the same, but its velocity increases, so its momentum changes.
* A ball thrown in the air: The ball's mass remains constant, but its velocity changes as it goes up and then down, causing its momentum to change.
* A satellite orbiting the Earth: The satellite's mass remains constant, but its velocity constantly changes direction to maintain its orbit, resulting in changing momentum.
