for every ________ there is equal and opposite ____
What is action; reaction?
What is the formula for speed and velocity?
Speed = distance / time
Velocity includes a direction
What are the units for speed?
m/s
How far an object moves in total
Distance
Which of Newton's Laws represents a person walking
What is Newton's Third Law?
The amount of matter in an object
What is mass?
What is the formula for force?
Force = mass x acceleration
What is it when an object speeds up, slows down, or changes direction?

Displacement
Which of Newton's Laws calculates the force used to accelerate a bicycle?
Newton's Second Law
I travelled 5mph east. This represents
What is velocity?
What is the formula for weight?
Weight = mass x acceleration due to gravity
Note: Acceleration due to gravity on earth = 9.8 m/s2
Who is the scientist who developed the Laws of Motion?
Sir Isaac Newton
What is the total distance of an object which moves 20 meters east and 40 meters north?
60 meters
This Newton's Laws represents the resistance to change of acceleration to an object
What is Newton's First Law?
The units for force
What are Newtons?
What is the formula for acceleration?
Acceleration = (Final velocity - Initial velocity) / time
What does this represent?
7 meters / 0.5 seconds = 14 meters/second
speed
What is the total displacement of an object which moves 50 meters east and 30 meters west?
20 meters east
This Newton's Laws represents a person jumping off the ground
What is Newton's Third Law?
How much space an object takes up
what is matter?
These three things can cause a change in acceleration
What are
1. Increase in speed
2. Decrease in speed
3. Change in direction
this represents
(50 meters/seconds - 10 meters/seconds) /10 seconds = 4 m/s2
What is Acceleration?
What is the total displacement of an object which moves 25 meters east, 10 meters north, 60 meters west, then 10 meters south?
35 meters west
