force cards

Opportunity/Strategy for you to Review
Complete note cards for the following list and use as a means to review. LEAVE THEM AT HOME, BY YOUR BED!!!!!!!!!
WRITE NEATLY SO THAT THE CARDS ARE A TOOL TO HELP YOU MEMORIZE MATERIAL.



Force: anything that changes the speed of an object; a push or a pull.

Net Force: overall force acting on an object

Unbalanced Forces: change the motion of an object

Balanced Forces: will not change the motion of an object.

Newton’s First Law of Motion: An object at rest will remain at rest and an object in motion will
remain in motion until some unbalanced force acts on it.

Newton’s Second Law of Motion: F = ma

Newton’s Third Law of Motion: For every action there is an equal an opposite reaction.

Momentum: a quantity of motion; Momentum = mass x velocity

Conservation of Momentum: the total momentum before and after objects interact is
the same.

motion cards

Motion: a change in position relative to some fixed object.

Reference Point: the fixed object used to determine another object’s motion.

Distance: The length between two points.

Speed: The distance an object travels in one unit of time

Formula for Speed: Distance / Time ( / means divided by )

Velocity: an object’s speed in a given direction.

Acceleration: the change in velocity over time. Three examples are : an increase in speed
a decrease in speed, or a change in direction

Formula for Acceleration : Final Velocity – Initial Velocity / Time for change
