Motion
This is the metric unit for length.
What is METER?
This is the equation for speed.
What is DISTANCE/TIME?
To determine ______________ you calculate the change in speed per unit of time.
What is ACCELERATION?
The definition for force.
What is PUSH OR PULL?
The tendency of an object to resist a change in motion.
What is INERTIA?
An object is in motion if it changes position relative to this.
What is a REFERENCE POINT?
You calculate this by dividing the total distance by the total time.
What is AVERAGE SPEED?
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?
The sum of all forces acting on an object.
What is NET FORCE?
The equation for Newton's Second Law.
What is FORCE = MASS x ACCELERATION?
Draw a graph of motion (distance vs. time) that shows constant speed.
What is a STRAIGHT LINE with SLOPE, like this: http://ritter.tea.state.tx.us/student.assessment/resources/online/2006/grade10/math/images/12graphicaa.gif
This is speed with direction.
What is VELOCITY?
The three ways you can accelerate.
What is INCREASING SPEED, DECREASING SPEED, and CHANGING DIRECTION?
This is the direction in which friction acts on an object.
What is opposite of the object's motion?
The more __________ a moving object has, the harder it is to stop. (Newton's Third Law)
What is MOMENTUM?
Draw a graph of motion (distance vs. time) that shows an object at rest.
What is a STRAIGHT LINE with NO SLOPE, like this: ------------------------------------------>
The average speed of a bicycle that traveled a total of 100 meters in 10 minutes.
What is 10 METERS PER MINUTE?
The two ways to graph acceleration are with distance vs. time and ...
What is SPEED VS. TIME?
This is the force of gravity on an object's mass.
What is WEIGHT?
The force on a 50 kg object accelerating at 2 m/s^2.
What is 100 NEWTONS?
Draw a graph of motion (distance vs. time) that shows acceleration.
What is a SLOPE getting STEEPER, like this: http://www.physics247.com/physics-homework-help/004o.jpg
The average speed of a car that traveled 10 meters in 10 minutes, then stopped for 20 minutes, then continued 30 meters in 10 minutes.
What is 10 METERS PER MINUTE?
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?
This type of friction acts on objects falling through the air.
What is AIR RESISTANCE?
The reaction force to the action force of you pushing on the ground to jump.
What is THE GROUND PUSHES BACK?
