Linear Motion
This is what all motion is relative to.
What is a reference point/frame of reference?
This type of motion is shown by a curved line on a d-t graph.
What is acceleration?
This the only thing that affects a body in free fall.
What is gravity?
This is the average speed and distance covered by a body that starts at 10 m/s and speeds to 20 m/s in 4 seconds.
What is 15 m/s and 60 m?
How does increasing the initial speed of a body affect its acceleration once it's in free fall?
It doesn't
This is the rate of change of displacement.
What is velocity?
First Hand $100
How are velocity and speed different?
This is the acceleration of an object moving at a constant velocity of 2,537 m/s.
What is 0?
First Hand $100
What are the 3 ways this object could accelerate?
This is the acceleration due to gravity (with units and direction).
What is -10 m/s2 down?
First Hand $100
When is gravitational acceleration not -10 m/s2?
This is the time taken for a body that starts at rest and accelerates at 6 m/s2 for 48 m.
What is 4 seconds?
This is what a negative slope getting steeper down means on a d-t graph.
What is speeding up backward?
This is the control on a car that changes its velocity but not its speed.
What is a steering wheel?
First Hand $100
What is the difference between vectors and scalars?
This is the final velocity of a body that starts from rest and accelerates at 5 m/s2 for 9 seconds.
What is 45 m/s?
This is how far an object would fall if dropped from rest and let fall for 4 seconds.
What is 80m?
First Hand $100
How fast will it be traveling at that point?
This is the acceleration of a body that speeds up from 20 m/s to 30 m/s over 50 meters.
What is 5 m/s2?
On Mars, the gravitational pull is half as strong. If you threw something straight up at a certain speed, how would the maximum height of the throw compare to the same throw on Earth?
It would go 2 times higher.
This is what the slope of a displacement-time graph tells us.
What is velocity?
This is the area under an acceleration-time graph.
What is velocity?
First Hand $100
What are traditionally the units of this quantity?
This is the vertical velocity of an object at the apex (peak) of its path when thrown into the air.
What is 0 m/s?
First Hand $100
What is the acceleration at the apex of the path?
This is the final velocity of a person who starts at 4 m/s and accelerates at 2 m/s2 over 5 m.
What is 6 m/s?
This is a rate of a rate.
What is acceleration?
This is the displacement of a student that walks forward with a speed of 5 m/s for 4 seconds, then runs backward with a speed of 10 m/s for 2 seconds.
What is 0 meters?
First Hand $100
What is the distance that the student travels?
What are the two things that could be happening when the slope of a v-t graph is positive?
Speeding up forward and slowing down backward
This is how much time a ball will be in the air if it is thrown straight up with an initial velocity of 30 m/s up.
What is 6 seconds?
This is the displacement of a student who starts at a speed of 20 m/s and decelerates by 2 m/s2 for 4 seconds.
What is 64m?
How do you spell your physics teacher's last name?
