Definitions from DEEP table Flashcards
Newton’s first law - linear
An object will remain at rest or in its current state of motion unless acted upon by an external force.
Newton’s second law - linear
The rate of acceleration of a body is proportional to the amount of force applied to it and the direction in which the force is applied.
Newton’s third law - linear
For every “action” there is an equal and opposite “reaction” force.
Force
A force is a “push” or a “pull” which alters the object’s state of motion (speeds it up, slows it down, stops it, changes its direction) and it can change the shape of an object.
Inertia - linear
The tendency of a body to resist change in its state of motion, whether that state is at rest or moving with a constant velocity.
Gravity
A constant force that pulls objects down towards earth.
Conservation of momentum - linear
The total momentum of the system before collision is equal to the total momentum after the collision.
Impulse
The change in momentum of a body.
Moment of inertia - angular
The tendency of a body to resist changes in its rotary motion.
Angular velocity
The rate of change of angular position of a rotating body.
Angular momentum
The amount of angular motion possessed by a body.
It is the product of the moment of inertia and the angular velocity of an object rotating around an axis.
Linear motion
Motion that occurs in a straight line or curved path.
Linear displacement
The movement of an object in a straight line along a single axis up and down or side to side.
Linear distance
The distance between two points.
Mass
A measure of the amount of matter an object is made up of.
