Force = Mass X Acceleration
What is Newton's 2nd Law?
A push or pull
What is a force?
For every action there is an equal and opposite reaction force.
What is Newton's third law of motion?
When forces are equal and opposite.
What is a balanced force?
The "pairs" in Newton's Third Law of Motion
What is action/reaction pairs?
Kg
What is the unit for mass?
The combination of all forces on an object.
What is the net force?
An object at rest will remain at rest and an object in motion will continue moving at a constant velocity unless acted upon by a net force.
What is Newton's First Law?
This increases when the mass of an object increases?
What is an object's inertia?
What is acceleration?
m/s2
What is the unit for Acceleration?
When the net force acting on an object is zero.
What is a balanced force?
A tendency to do nothing or remain unchanged.
What is inertia?
Forces that are opposite in direction and not equal.
What is an unbalanced force?
Action: A book presses down on a table
Reaction: What is the table pressing up on the book?
Newtons
What is the unit for Force?
When force causes an object to move.
What is an unbalanced force?
Think acceleration.
What is a decrease in acceleration?
The more inertia an object has.
What is more mass?
Action: A tennis ball pushing against the floor.
Reaction: What is the floor pushing against the tennis ball?
The force that pulls objects to the center of the Earth.
What is Gravity?
The formula for calculating force.
What is mass x acceleration?
These were formulated by Sir Issac Newton.
What are Newton's Laws of Motion?
This causes an object that is moving to stop or start an object moving.
What is a force?
Action: Guy pushing on a piano.
Reaction: What is the piano pushing back on the guy?
