The shortest distance between two points
What is Displacement?
Mary Anne and her friend Abe are playing tug of war with a rope. Does the rope's length represent distance or displacement?
What is displacement?
Convert 18 kilometers an hour into meters per second squared
5 meters per second squared
To find the _______, simply divide the total distance from the total time
What is average speed
A distance and displacement can be the same
True. If the distance is 2 miles north, then the distance and displacement would both be 2 miles
distance divided by time
What is speed?
Maya is taking, when she gets stuck on one of the questions. Help her out.
What is divided into time when finding speed?
A) Displacement B) Gravity
C) Inertia D) Distance
D) Distance
A car accelerates from a stop to a speed of 36 km/hr in 5 seconds. What was its acceleration.(in m/s)
2 m/(s^2)
A _____ - ________ graph is used to determine speed
what is Distance - Time
When riding inside a bus, a car in the following lane would be a good frame of reference?
False. The char in the following lane is not stationary, and therefore incapable of being a reference point
the length of path followed
What is Distance
Jason's teacher is teaching about distance and displacement, but Jason slept through some of the lecture. Help Jason answer the question on the board:
The total distance between point A and point B is ________
displacement
A train slows down to a station. It's initial velocity was 10.8 km/hr, but it slowed down to a complete stop in 30 seconds. What was its acceleration?
-0.1 m/(s^2)
When something travels an equal distance in equal intervals of time, it traveled in _______ ____
What is Uniform Motion
Acceleration is only when an object speeds up?
False. Acceleration is when an object changes its velocity, which can be both speeding up and slowing down.
Something stationary to its observer that is used to detect motion
What is a Frame of Reference?
James decides to go to his friend's home. He travel's 1 block north and 3 blocks east. In total, he traveled 4 blocks. Is this an example of distance or displacement?
Distance
To achieve an acceleration of 3 m/(s^2) in 40 seconds from a stand still speed,what must the speed be in m/s?
1,200 m/s
____ is a push or pull
What is force
Force and motion are always around us?
True. Force and motion are visible through all parts of the day, whether it be on the road, at a school/workplace, or at home.
The rate of change in velocity. (It can be a change in speed OR direction)
What is acceleration
As a work out, Mark runs around his neighborhood every morning. He runs 3 miles west and 4 miles north, to his sister's house. Does a trail between his home and his sister's represent distance or displacement?
Displacement
When solving a conversion, what almost ALWAYS goes with the answer?
A) v/(s^2) B) y/x^2
C) m/(s^2) D) ft/(km^2)
C) m/(s^2)
When there is no acceleration, the speed is _____
What is constant
Speed and velocity are the same thing?
False. Speed deals with distance traveled while velocity deals with distance in a given direction.
