Vectors, Distance and Displacement
Which of the following is a vector? Time, Speed, Velocity, or Distance
What is velocity
A car travels 100 m north in 50 seconds. What is it's average velocity
v = d/t a = Vf-Vi/t
What is 2 m/s
In physics, when objects fall to the ground, they travel in this direction
What is negative
When an object is thrown upward into the air, its velocity is this at the highest point
What is 0 m/s?
An object can accelerate in 3 ways, speed up, slow down, or by doing this
What is change direction
By definition, Vectors have both
What is Magnitude and Direction
A car travels at a velocity of 5 m/s west for 30 seconds. How far did the car travel?
v = d/t a = Vf-Vi/t
What is a 150 m
When an object falls to the ground its acceleration is approximately
What is -10 m/s2
When a feather and a rock are dropped in a vacuum from the same height at the same time, which one hits the ground first
What is they both hit the ground at the same time
When a car slows down, this type of acceleration is occurring
What is negative acceleration
A man walks 20 m North and 40 m South. The distance the man walked is
What is 60 m
A car speeds up from 35 m/s to 65 m/s in 5 seconds. What is it's acceleration
v = d/t a = Vf-Vi/t
What is the 6 m/s2
A book takes 2 seconds to hit the ground. The speed on the book when it hit the ground was
d = (0.5)at2 Vf = at
What is -20 m/s2
When an object is thrown upward into the air, its velocity does this as it travels up
What is decreases, slows down
Which is an example of acceleration
A car traveling at 30 m/s east, A car sitting at a red light, or A car traveling around a corner at 5 m/s
What is a car traveling around a corner at 5 m/s
A man walks 80 m east and 30 m west. The man's displacement is
What is 50 m east
A car slows down from 30 m/s to 5 m/s in 10 seconds. What is it's acceleration
v = d/t a = Vf-Vi/t
What is -2.5 m/s2
An apple falls to the ground for 5 seconds. The distance the apple fell was
d = (0.5)at2 Vf = at
What is -125 m?
When an object is thrown upward into the air, its velocity does this as it travels down
What is increases, speeds up
A car speeds up traveling east on a highway. The car's acceleration while speeding up would best be described as
What is positive acceleration
A woman walks 8 m east then 6 m south. The woman's distance and displacement are
What are 14 m and 10 m SE
A car is stopped at a red light. When the light turns green the car speeds up at 7 m/s2 for 8 seconds. What is its final velocity?
v = d/t a = Vf-Vi/t
What is 56 m/s
An object falls 20 m to the ground. The time it takes the object to hit the ground is
d = (0.5)at2 Vf = at
What is 2 s
When an object is thrown upward into the air, the objects acceleration is this the entire time it is in the air.
What is -10 m/s2?
A car slows down from 140 m/s to 60 m/s in 10 seconds. The car's acceleration is
What is none (- 8 m/s2)
