At what point(s) on a slope does a rolling ball have the least kinetic energy?
A. The highest points on the slope
B. The middle of the incline
C. The "valley" of the slope
A

Newton's First Law of motion states...
...an object at rest remains at rest unless acted upon by a force. An object in motion remains in motion, unless acted upon by a force.

Find the final velocity of a ball that was dropped from rest at 4 s. (HINT: V(f) = acceleration x time + initial velocity)
V(f) = (10 m/s^2) x (4 s) + (0 m/s) = 40 m/s

What happens to two objects if they collide in an elastic collision?
They bounce back off of each other
200
What do the arrows on an FBD represent?
Each of the forces present on an object.

The very first song that Mr. Meador ever wrote was a rap song called what...
"Les Sciences", in French: "The Sciences"
300
Newton's Second Law states...
... (Force) = (mass) x (acceleration)
or just
F = m x a
300
In any type of collision, these two quantities are always conserved. ALWAYS!
Energy & Momentum

What happens to two objects if they collide in an inelastic collision?
The two objects stick together
300
Does the length of the vectors in a FBD matter?
Yes!! The length gives a relative measure of the force so that we can compare the strength of one force to that of another force.

At what point(s) on a slope does a rolling ball have the least potential energy?
A. The highest points on the slope
B. The middle of the incline
C. The "valley" of the slope

Newton's Third Law states...
... every action has an equal and opposite reaction.

At what point(s) on a slope does a rolling ball have the greatest potential energy?
A. The highest points on the slope
B. The middle of the incline
C. The "valley" of the slope

Car A (with a mass of 10 kg) is traveling towards stationary Car B (with a mass of 5 kg) with a velocity of 2 m/s. After their collision, Car A completely stops and Car B is now moving. What is the velocity of Car B after the collision?
befo' (m1 x v1) + (m2 x v2) = afta' (m1 x v1) + (m2 x v2)
(10kg x 2m/s) + (5kg x 0m/s) = (10kg x 0m/s) + (5kg x v)
20 + 0 = 0 + 5v --> 20 = 5v --> v = 4 m/s
