What is the difference between distance and displacement?
Distance -length of path
Displacement- distance between initial and final positions
What is the First Law of Motion?

Why does a person with a parachute not die upon impact when falling down to Earth?
Due to air resistance with air particles hitting the entire surface area of the object
Drake was running through the 6 with his woes for 260 meters in 50 seconds, what was his velocity?

What is the initial velocity of a free fall?
Vi=0
A cheetah starting from rest, accelerated at 7 m/s2 for 3 s. How far, in meters, did the cheetah travel during that time?
Δx = vit + ½at2
Δx = (0m/s)(3s) + ½(7m/s2)(3s)2
Δx = 0m + ½(7m/s2)(9s2)
Δx = 31.5m
What is the direction of centripetal acceleration in circular motion?
Towards center of circle
A force of 10 N acts on a 2 kg object for 4 s. What is the change in momentum (impulse) of the object?
40 N.s
Yeah, my receipts, be lookin' like phone numbers

A baseball is thrown up with an initial velocity of 24 m/s. How high will it have traveled after 3.4 seconds?
dy=23.8 meters
