Newton's Laws
Commonly referred to as the Law of Inertia
What is Newton's 1st Law of Motion?
An action that can change an object's motion
What is force?
The force due to gravity (equal to the product of the object's mass and the acceleration of gravity)
What is weight?
The process of an object changing position
What is motion?
The transfer of energy when a force moves an object over a distance
What is work?
The tendency of an object to resist a change in motion
The unit used to measure force
What is a newton?
The force against motion
What is friction?
A set of laws created by Sir Isaac Newton, which explain how objects tend to move
What is Newton's Laws of Motion?
Machines that work with one movement
What is a simple machine?
States that the net force of an object is equal to the product of its mass and acceleration
What is Newton's 2nd Law of Motion?
The combination of all forces acting on an object
What is net force?
A force that pulls objects towards each other
What is gravity?
The distance an object moves over time
What is speed?
The force applied to a simple machine
What is effort force?
The equation for Newton's 2nd Law
What is F = ma?
Forces that are opposite in direction, equal in size, cause no change in motion, and have a net force of 0
What is a balanced force?
The value of gravity on Earth
What is 9.8 m/s2?
The measure of speed in a given direction
What is velocity?
The force exerted by a simple machine
What is resistance force?
States that for every action, there is an equal, opposite reaction
What is Newton's 3rd Law of Motion?
Forces that are not opposite or equal
What is an unbalanced force?
True or False: A ball rolling on a smooth surface with no outside forces acting on it will continue rolling indefinitely
What is true?
Found by dividing the change in the velocity of the object by the change in time
What is acceleration?
The number of times a machine multiplies the effort force
What is mechanical advantage?
