100
The formula for calculating average velocity using velocities.
v_(avg)=(v+v_0)/2
100
This is Acceleration
What is rate of change of the velocity of an object?
100
This is free fall.
What is when an object falls with only acceleration due to gravity acting on it?
100
This is what the slope of a position-time graph represents.
What is velocity?
100
If initial velocity is 10 m/s and a is negative, what can you use to find stopping distance
What is v^2=v_0^2+2ax
200
This is how instantaneous velocity differs from average velocity
Instantaneous velocity is the velocity at an exact moment vs. average velocity is the typical velocity across an extended period of time
200
The formula for calculating acceleration
What is
a=(v-v_0)/t
or
a=(\Deltav)/t
200
The acceleration due to gravity near the surface of Earth.
What is 9.81 m/s^2
200
This is how you can determine displacement from a velocity-time graph.
What is take the area under the curve?
200
These affect the terminal velocity of a falling object.
What is mass, shape, viscosity, and initial velocity?
300
The velocity of an object that travels 50 meters in 5 seconds.
What is 10 m/s?
300
The acceleration of an object moving at a constant speed.
What is
0 m/s^2?
300
The velocity of a ball thrown upwards at its maximum height.
What is 0 m/s?
300
This is what a curved line on a position-time graph signifies.
What is accelerated motion?
300
This true for the velocity of an object traveling in a circle.
What is it is accelerating because the direction changes?
400
The average velocity when a car accelerates from rest to 20 m/s in 10 seconds.
What is 10 m/s?
400
Acceleration of a car that increase speed from 20 m/s to 50 m/s in 5 seconds.
What is
6 m/s^2?
400
The time in which a ball will reach the ground when dropped from a height of 20 meters.
What is 2.02s?
400
A description of the motion from 15 – 40 seconds on the position vs. time graph below
What is traveling at a constant rate in the negative direction past your initial position?
400
This is true for the velocity and acceleration of one car passing another.
What is it is moving faster but not necessarily accelerating?
500
The average velocity (in m/s) if a cyclist travels 30 km in 1.5 hours.
5.55 m/s
500
Distance covered by a train that slows down from 80 m/s in 10 seconds with a deceleration of 6 m/s^2 .
What is 500 m?
500
The height a rock reaches when thrown upwards with an initial velocity of 15 m/s.
What is 11.47m?
500
The vertical motion depicted by the velocity-time graph below.
What is an object thrown in the air?
500
This is a problem that can be solved using this equation:
v^2+v_0^2+2ax
