Motion
This is the equation for speed.
What is DISTANCE/TIME?
Two boxes have different masses but the same force.
What is different accelerations?
The sum of all forces acting on an object.
What is NET FORCE?
The tendency of an object to resist a change in motion.
What is INERTIA?
A car traveling at constant speed
What is a balanced force?
You calculate this by dividing the total distance by the total time.
What is AVERAGE SPEED?
Two boxes have the same mass but different forces.
What is different accelerations?
This opposing force makes it difficult to accelerate while pulling a heavy object.
What is FRICTION?
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
Velocity has speed with direction, speed has no direction.
What is the difference between velocity and speed?
The three ways you can accelerate.
What is INCREASING SPEED, DECREASING SPEED, and CHANGING DIRECTION?
The cell phone sits motionless on the teacher's desk.
What is balanced force?
The fuel of a space shuttle burns downward and the shuttle is pushed upward.
What is Newton's 3rd Law?
Draw a graph of motion (distance vs. time) that shows acceleration.
What is a curved 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 motorcycle and motorcyclist had a mass of 60.0kg, its acceleration was 29.0 m/s2. What is the net force?
What is 1,740N ?
Mrs. Maloney pulled with 200N left and Jace pulled with 20N right.
What is 180N left ?
The reaction force when you push on the ground to jump.
What is THE GROUND PUSHES BACK?
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?
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?
Santa's sleigh landing on the rooftop, his gifts sliding across the floor, & the reindeer wagging their tail
What is an unbalanced force?
The force on a 50 kg object accelerating at 2 m/s^2.
What is 100 NEWTONS?
