Newton's Laws
Which law states that objects at rest will remain at rest?
1st law - law of Inertia
When forces are _____ there is no change in motion
Balanced, equal zero
What is force?
a push or pull exerted on an object
False - the first law
Who discovered the Three laws of Motion and when?
Sir Isaac Newton in the 1700's
What is Newton's Third Law?
For every action, there is an equal and opposite reaction
When forces are _______, it causes objects to move
unbalanced
What is inertia?
The tendency of an object to resist any change in motion
Usually less than one force acts on an object at a time
False - many forces
Which law is best shown: You are in a car, when the breaks are slammed. Your body leans hard against the seatbelt.
First law of Inertia
What are the measurements involved in the second law?
Force = mass x acceleration
When forces act on an object and their net force is zero, the ojbect does not move.
balanced
The rate at which velocity changes
acceleration
The measure of force is calculated in Newtons
What does it mean when forces act on an object and they equal zero
they are balanced
Objects in motion will remain in motion
Newton's First Law
Produces a net force greater than zero
unblanaced
Describe mass
a measure of how much matter is within an object
The product of all the forces acting on an object is net force
False the sum
When playing tug of war and the rope isn't moving ... are the forces balanced or unbalanced?
balanced
The second law explains that when an acceleration is changed, it also impacts the ...
Force
The object acted upon moves in the direction of the greater force
unbalanced
The overall force acting on an object when all the individual forces acting on it added together is ....
Net force
Friction impacts how much force is needed to make an object move
True
very briefly describe the three laws of motion
1. Inertia
2. F = m x a
3. Action Reaction
