Newton's Laws
100

Draw a graph of motion (distance vs. time) that shows an object returning to the origin.

The line begins away from the origin and has a negative slope.

100
This is the equation for speed.
What is DISTANCE/TIME?
100

To determine ______________ you calculate the change in velocity per unit of time.

What is ACCELERATION?

100
The definition for force.
What is PUSH OR PULL?
100
The tendency of an object to resist a change in motion.
What is INERTIA?
200

An object is in motion if it changes this.

What is POSITION?

200
You calculate this by dividing the total distance by the total time.
What is AVERAGE SPEED?
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
The equation for Newton's Second Law.
What is FORCE = MASS x ACCELERATION?
300
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
300
This is speed with direction.
What is VELOCITY?
300
The three ways you can accelerate.
What is INCREASING SPEED, DECREASING SPEED, and CHANGING DIRECTION?
300

Type of force that does NOT result in acceleration.

What is BALANCED FORCE?

300

The greater an object's ______, the more force is required to cause acceleration.

What is MASS?

400
Draw a graph of motion (distance vs. time) that shows an object at rest.
What is a STRAIGHT LINE with NO SLOPE, like this: ------------------------------------------>
400
The average speed of a bicycle that traveled a total of 100 meters in 10 minutes.
What is 10 METERS PER MINUTE?
400

What is 8.6N?

400

Type of forces acting on an object traveling at a constant rate of speed.

What is BALANCED FORCE?

400

The force on a 50 kg object accelerating at 2 m/s2.

What is 100 NEWTONS?

500
Draw a graph of motion (distance vs. time) that shows acceleration.

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?
500

The rate of an acceleration of a 2.5 kg book if a force of 20N is applied.

What is 8 m/s2?

500

Causes an object to change its motion.
