Two balls, ball one of mass m and ball two of mass 2m, are falling to the ground. Assume there is no air resistance. Which ball will hit the ground first?
What is neither/same time?
200
The equation for acceleration? Multiple answers accepted.
What is A = fnet/m , change in v divided by t , etc.?
200
The slope of a velocity vs time graph
What is acceleration?
200
The equation for average velocity.
What is the change in position divided by time or displacement divided by time?
200
The overall change in position
What is displacement?
300
the description of velocity represented by a straight line parallel with the x-axis in a position vs. time graph
What is zero?
300
Is acceleration a scalar or a vector quantity? Explain.
What is Vector, because it requires a direction as well as a magnitude?
300
The p-t graph of an object who is originally at rest then travels in a positive direction at a constant velocity.
What is a diagonal line with a constant, positive slope?
300
Is velocity a scalar or a vector quantity? Explain.
What is a vector quantity? Because velocity requires a direction and magnitude. Just a magnitude would be speed.

A couple is traveling in a car to a neighboring town. The town is 46,800 meters away from their house, they reach it in an hour. Assuming the trip was all in one linear direction, what is their average velocity during this trip?
What is 13 m/s?
400
A bullet is fired horizontally, it is in the air for 8 seconds before it hits the ground and comes to a stop. With air resistance being negligible, how far has the bullet traveled?
What is 313.6 m (using g=9.8)?
400
the sign of acceleration of a car decreasing its velocity in the negative direction
What is positive?
400
The v-t graph of an object who is initially traveling at a positive velocity before decelerating at a constant rate to a stop.
What is a diagonal line, with a non-zero y-intercept, that has a constant negative slope?
400
A ball is dropped at a known height, a ball with the same mass, under the same circumstances, is dropped a second later. They both hit the ground at the same time. What could cause this?
What is the second ball had an initial velocity?
400
A nerf bullet is shot out of a nerf gun while another is dropped from the hand of a student at the exact same moment. Which accelerates vertically faster?
What is neither, they are both in free fall and will hit the ground at the same time?
500
Assume the slope of the graph is 9.8 m/s^2, with upwards movement being positive. Is this graph representative of free fall?
What is the No, the slope should be negative?
500

2 - Constant speed (faster than 4),
3 - Deccelerating,
4- Constant speed (slower than 2)?
500
The area under an a-t graph.
What is the change in velocity?
500

What is 16.7 m/s?
500
A motorcycle accelerates from rest at a constant rate for 500m until it reaches a maximum velocity of 23 m/s. What is the acceleration while the motorcycle is accelerating?
What is .529 m/s^2?
