MOTION IN A STRAIGHT LINE

Flashcards to help review lecture notes and prepare for an upcoming exam.

Mechanics

The branch of physics that deals with the conditions of rest or motion of material objects around us.

Statics

The branch of mechanics dealing with objects at rest or in equilibrium.

Kinematics

The branch of mechanics focusing on the motion of objects without considering the cause of motion.

Dynamics

The branch of mechanics that studies the motion of objects, taking into account the cause of their motion.

Rest

When an object does not change its position with respect to its surroundings with the passage of time.

Motion

When an object changes its position with respect to its surroundings with the passage of time

Point Object

An object whose position changes by distances much greater than its own size in a reasonable time.

Frame of Reference

A coordinate system with a clock used to specify the position of an object and measure time.

One Dimensional Motion

Motion where only one of the three coordinates specifying the position of the object changes with time, resulting in movement along a straight line.

Two Dimensional Motion

Motion where two of the three coordinates specifying the position of the object change with time, resulting in movement along a plane.

Three Dimensional Motion

Motion where all three coordinates specifying the position of the object change with time, resulting in movement in space.

Derivative of a Constant

The derivative of every constant function is zero.

Power Rule

The derivative of x^n is equal to n*x^(n-1).

Sum Rule

The derivative of the sum of two differentiable functions is the sum of their derivatives

Velocity

The slope of the position-time graph gives the of the object
