Momentum is a measure of an object's motion, determined by its mass and velocity. It is a vector quantity, meaning it has both magnitude and direction.
Momentum is calculated by multiplying an object's mass by its velocity. The formula for momentum is: p = mv, where p is momentum, m is mass, and v is velocity.
The change in momentum represents the force applied to an object over a period of time. It is also known as impulse and is measured in Newton-seconds (N∙s).
To calculate the change in momentum of a launched object, you need to know the mass of the object, the angle at which it is launched, and its initial velocity. The formula for change in momentum is: Δp = mΔv = mvf - mvi, where Δp is change in momentum, m is mass, and vf and vi are final and initial velocities, respectively.
Momentum is measured in kilogram-meters per second (kg∙m/s), while change in momentum is measured in Newton-seconds (N∙s).
