Ch4. Momentum Flashcards
Is momentum scaler or vector
It is a vector quantity
What is the relationship between the momentum and the force applied
There is a proportional relationship between the rate of increase momentum and the force applied
What is the equation of force relating to momentum
Force = change in momentum /time taken
Is momentum conserved or not?
Momentum is conserved
Momentum before collision = momentum after collision
Went two objects collide and stick together, what is this collision called
Inelastic collision
What is Newton’s first law
Things don’t speed up, slow down or change direction unless you push (or pull) them
What is Newton’s second law
The bigger the force acting on an object is, the faster the object will speed up.
Objects with greater mass require a bigger forces than those with smaller mass to make them speed up (accelerate) at the same rate
what is the equation for momentum
Momentum=. Mass X velocity
