2 cards from this section. Quick, good the night before a test.
What is the formula for momentum?
Think about mass and velocity.
What does F = ma stand for?
Consider how mass relates to how fast something can change speed.
What is the product of an object's mass and velocity called?
It's a vector quantity related to how fast and in what direction an object moves.
True or False: Newton's Second Law states that a net force is needed to keep an object in uniform motion.
Reflect on Aristotle's and Newton's views on motion.
A 2 kg cart is pushed with a net force of 10 N. Find the cart's acceleration and its momentum after 5 seconds.
Use F = ma for acceleration, then find the final velocity.
A football (mass 0.5 kg) is kicked and achieves a momentum of 15 kg·m/s. What was its velocity?
Rearranging the momentum formula will help you solve for velocity.
