An location to which you compare other locations.
What is Reference Point?

Which line is moving at a faster speed?
What is Line A?

A force that resists motion by converting kinetic energy into heat (causing things to slow down).
What is Friction?

A ball is projected into the air. Describe what happens to the ball's potential energy, from beginning to end.
What is it increases then it decreases. (It starts at 0% at the bottom, goes to 100% at the top, then back to 0%).

The rate of change of velocity.
What is Acceleration?

What is happening to the speed of the racehorse?
What is it's increasing/accelerating?

What is the Net Force in this game of Tug-of-War?
What is 0 N?
(forces are balanced)
Weight changes depending on where you are in the universe. The amount of weight an object has depends on its ______, which remains constant no matter its location in the universe.
What is Mass?
What is the equation that connects mass and acceleration to force in Newton's Second Law?
What is Force = Mass x Acceleration?
The sum of an object's kinetic energy and potential energy
What is Mechanical Energy?
Joe can pitch a baseball a distance of 48 meters in 1.5 seconds. How fast is his pitch? (must include units in answer)
What is 32 m/s?
During what point of time is the car not moving?
What is from 0.75 to 1.25 hours?

What is the Net Force of the object?
What is 3 N Down/South?
(forces are unbalanced)
Why does Earth orbit the Sun rather than any other body in the solar system?
What is Mass?
Or "because the Sun has the most mass"?
The Earth continues to orbit the Sun because there's no friction to slow it down. Which law?
What is Newton's First Law?
What is the Law of Conservation of Energy?
What is "energy cannot be created nor destroyed"?
Which ball is moving with the fastest speed? YOU HAVE DOUBLE TIME
What is Ball 1?

How much faster is Runner A than Runner B? YOU HAVE DOUBLE TIME
What is twice as fast?
When gravity is the only force acting on an object.
What is Free Fall?
Weight is measured with a _______ (instrument) in _______ (unit).
What is Spring Scale and Newtons?
A swimmer pushes back on the water and is propelled forward. Which law?
What is Newton's Third Law?
A student places a marble at the top of a ramp and releases it. The marble rolls down and then climbs partway up another ramp. The marble doesn't reach the same height it started at because some of the kinetic energy is converted into _____ and _____.
What is Sound and Heat?

Jack lives 3 miles from school and can walk home in 45 minutes. How fast does Jack walk in miles per hour? YOU HAVE DOUBLE TIME
What is 4 mi/hr?

What is the average speed of the car from 1 hour to 3 hours? YOU HAVE DOUBLE TIME
What is 0.5 km/hr?
At 1 hour, the car is at 50 km. At 3 hours, the car is at 150 km.
Avg speed = total distance / total time
Avg speed = 100 km / 2 hr
Avg speed = 0.5 km/hr
