p=mv, where p is momentum, m is mass, and v is velocity.
What are the units for momentum?
Kilogram meters per second (kg⋅m/s).
Is momentum a scalar or vector quantity?
Momentum is a vector quantity.
What does it mean for momentum to be a vector?
It has both magnitude and direction.
How is Newton's Second Law derived from momentum?
Start with p=mv. 2. Differentiate with respect to time: dtdp=dtd(mv). 3. If mass is constant: dtdp=mdtdv. 4. Since a=dtdv: dtdp=ma. 5. And since F=ma, we get: F=dtdp.
What are the differences between momentum and kinetic energy?
Momentum: Vector, measures mass in motion. Kinetic Energy: Scalar, relates to an object's capacity to do work.
