Alright honey, be careful! Love you too, bye!
Hey mom, I'm leaving for school now! See you around three! Love you, bye!
Well, off to science class! I wonder what she's going to say?
She said that today we'd be learning about the third law of motion...
Momentum (kg m/s)=mass (kg) x velocity (m/s) P=mv
The unit for momentum is kg x m/s. Notice that momentum has a direction because velocity has a direction.
A moving object has a property called momentum that is related to how much force is needed to change its motion.
The momentum of an object is the product of its mass and velocity. Momentum is given the symbol p and can be calculated with the equation on the board.
