projectile motion
The speed of light in miles per second
What is 186,282 miles per second?
unit for velocity
m/s
Newtons first name
Who is Isaac?
It takes this much time for a rock to fall to the ground from the top of a 40m cliff
What is 4 seconds?
This quantity represents the overall change in position rather than the total distance traveled
What is displacement?
Uniform, average, and instantaneous are all forms of this
What is velocity?
unit for acceleration
m/s/s
cinemática is kinematics in what language?
spanish
A ball hits the ground with a velocity of 80 m/s after being thrown down from with a velocity of 20 m/s from the top of a tower with this height (g = 10m/s2)
What is 300m ?
The slope of a velocity v. time graph represents this value
What is acceleration?
The difference between speed and velocity
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement
Rock X is released from rest at the top of a cliff that is on Earth. A short time later, Rock Y is released from rest from the same location as Rock X. Both rocks fall for several seconds before landing on the ground directly below the cliff. Frictional forces are considered to be negligible.
After Rock Y is released from rest several seconds after Rock X is released from rest, what happens to the separation distance S between the rocks as they fall but before they reach the ground, and why? Take the positive direction to be downward
S increases because at all times Rock X falls with a greater speed than Rock Y.
Velocity is different from speed in that it is this type of quantity
What is a vector quantity?
The displacement of an object must be this if there is 0 distance traveled
What is 0?
