The tendency of an object to resist a change in motion.
What is INERTIA?
200
An object is in motion if it changes position relative to this.
What is a REFERENCE POINT?
200
You calculate this by multiplying the average velocity by the total time.
What is displacement?
200
This is why the moon is still considered to be accelerating, even if it moves at a constant speed around the Earth.
What is CHANGING DIRECTION?
200
The sum of all forces acting on an object.
What is NET FORCE?
200
Newtons second law says More force results in
What is MORE ACCELERATION?
300
Draw a graph of motion (position vs. time) that shows constant velocity.
What is a STRAIGHT LINE (constant slope)
300
This is speed with direction.
What is VELOCITY?
300
An object moving with a positive velocity that begins to speed up has this type of acceleration
What is positive?
300
This friction acts on object that are not moving.
What is STATIC FRICTION?
300
The more __________ a moving object has, the harder it is to stop.
What is MOMENTUM?
400
Draw a graph of motion (position vs. time) that shows an object at rest.
What is a STRAIGHT LINE with NO SLOPE, like this:
------------------------------------------>
400
The average velocity of a bicycle that traveled a total of 100 meters in 10 minutes.
What is 10 METERS PER MINUTE?
400
An object moving with a negative velocity that begins to slow down has this type of acceleration
What is positive?
400
This is where an object is when the normal force is equal and opposite to the force of gravity
What is on a flat surface?
400
This is calculated by: force times the duration that the force occurs
What is IMPUSLE?
500
Draw a graph of motion (position vs. time) that shows acceleration causing an object to speed up.
SLOPE getting STEEPER
500
The average velocity of a car that traveled 10 meters in 10 minutes, then stopped for 20 minutes, then moved 30 meters in 10 minutes.
What is 1 METERS PER MINUTE?
500
The average acceleration of a bicycle that started at the top of a hill with a speed of 4 m/s and ended at the bottom of the hill with a speed of 8 m/s if the entire ride took 2 seconds.
What is 2 METERS PER SECOND SQUARED?
500
This type of force acts on objects falling through the air.
What is AIR RESISTANCE?
500
The resulting force of you pushing on the ground to jump.
