This law explains why when you kick a soccer ball it goes flying and you feel the force on your foot in the opposite direction.
What is Newton's Third law of motion?
100
What is the unit for force?
Newtons (N)
200
What is Newton's First Law of Motion?
What is if an object is at rest it will stay at rest, if an object is in motion it will stay in motion until acted upon by an unbalanced force.
200
A force that slows down objects when they rub against each other
What is friction?
200
What formula would you use to find force?
mass x acceleration
200
What is Newton's Third Law of Motion?
the Law of Motion that states for every action there is an equal and opposite reaction....
200
Who discovered the laws of motion?
Who is Isaac Newton?
300
A change in position
What is motion?
300
On a graph showing distance versus time, which type of line indicates no motion?
What is a horizontal line?
300
What is the net force?
What is 0 Newtons?
300
Newton's second Law of Motion states that an object with more mass...
requires more force to accelerate

Explain why a rocket can continue to move in space without the use of its engines.
The rocket has inertia. Since space is a vacuum there is no air resistance or friction to slow or stop the rocket.
400
An object's resistance to any change in motion
What is inertia?

50 N right and 60 N left will result in.
10 N left

A change in a moving object's speed or direction is..
What is Acceleration?
400
Interpret the graph below?
What is constant speed?
400
This is the force of attraction among all objects with mass
What is gravity?
500
What is the formula to calculate speed?
What is distance divided by time?
500
What is the following graph illustrating below?
What is an object is accelerating?
500
How will this object move?
What is it will move to the right?

Use at least one of the laws of motion to explain why a bowling ball would not go as far as a golf ball if hit with the same amount of force by a baseball bat.
According to the 2nd law, objects with more mass need greater forces to accelerate. The bowling ball has more mass and therefore will need more force.
(Answers might vary!)

Causes an object to start or stop moving, accelerate or change direction.
Unbalanced Force
