Two skiers with the same mass are on Baldy. One is close to the top, one is halfway down. They are both going the same speed.
Which one has more Potential Energy?
One at the top.
Big Chungus wants to lose weight. He decides to go to Mars.
Does he weigh less? Explain.
Yes.....
What is the difference between Speed and Acceleration?
Speed: Distance covered over time
Acceleration: Change of Speed over time
Who had the greater acceleration rate?
Skydiver A going 150m/s pulls his chute and 7 seconds later is going 10m/s.
skydiver B jumps out of the plane and accelerates from the force of gravity.
What was their rate of acceleration?
A: -20m/s/s
B:10 m/s/s
Mr. Newton has a mass of 100kg. How much does he weight?
1,000 N
(forget to multiply by gravity?)
Two skiers with the same mass are on Baldy. One is close to the top, one is halfway down. They are both going the same speed.
Which one has more Kinetic Energy?
They have the same amount.
Same mass, same speed.
Who is Mr. Newton's favorite student?
I have 88 students tied for first :)
