What is terminal speed?
The speed before the terminal death of a superhero
The speed of an object with the acceleration of gravity and the air resistance taken into account no matter what shape it is.
The speed an object has after the air resistance builds up to be the same as the weight of the object. The 3 things that terminal speed depends on are weight, shape and air resistance.
In what direction is centripetal force?
Towards the center of the circle
Tangential
Opposite the middle of the circle
If you exert an 80 newton force on the ground, how much force is the ground exerting on you?
80 newton
40 Newton
160 Newton
Equation for momentum?
P=MT
P=MV
P=FT
Equation for impulse?
J=MA
J=MV
J=FT
Law of Conservation of Momentum
Everything likes to come back to being still
When a collision occurs between item 1 and item 2, the total momentum of the two items before the collision is the total momentum of the two items after the collision. That is the momentum lost by item 1 is gained by item 2.
When a collision occurs between two items, one item takes on more of the momentum
