KINEMATICS (PHYSICS LESSON 3)

motion

IS DEFINED AS A CONTINUOUS CHANGE IN POSITION OF AN OBJECT OVER TIME RELATIVE TO A FIXED STARTING POINT.

motion

IS THE DISPLACEMENT OF AN OBJECT IN RELATION TO OBJECTS THAT ARE CONSIDERED TO BE STATIONARY.

displacement

The total change in the object's position along with the direction of motion.

displacement

is a vector quantity that refers to "how far out of place an object".; it is the

object's overall change in position.

displacement

you need to consider its direction which represents the direction from the initial position to the final position.

displacement

does not depend on the path taken by an object but only on its initial and final

position.

distance

Total path covered by the object in motion

distance

is a scalar quantity that refers "how much ground an object covered" during its motion

velocity

The rate at which an object changes its position

velocity

is a vector quantity that refers to "the rate at which an object changes its position."

speed

Describes how fast an object moving

speed

is a scalar quantity that refers to "how fast an object is moving."

speed

The distance covered by an object over time which motion occured.

speed

can be thought of as the rate at which an object

average speed

IS DEFINED AS THE RATIO OF DISTANCE TO TIME INTERVAL.

average velocity

IS DEFINED AS THE RATIO OF DISPLACEMENT TO TIME INTERVAL.

Instantaneous Velocity

IS THE LIMIT OF THE AVERAGE VELOCITY AS THE TIME INTERVAL

APPROACHES ZERO (0) OR INSTANTANEOUS RATE OF CHANGE OF POSITION WITH TIME.

Instantaneous Speed

IS THE MAGNITUDE OF INSTANTANEOUS VELOCITY.

acceleration

IS DEFINED AS THE RATE OF CHANGE OF VELOCITY

acceleration

IS A VECTOR QUANTITY WHEREIN IT COULD BE POSITIVE OR NEGATIVE AND IT CAN ALSO BE ZERO

Average Acceleration

PARTICLE IS DEFINED AS THE RATIO OF THE CHANGE OF VELOCITY TO THE CHANGE OF TIME.

Instantaneous Acceleration

IS THE LIMIT OF THE AVERAGE ACCELERATION AS THE TIME INTERVAL APPROACHES ZERO (0) OR INSTANTANEOUS RATE OF CHANGE OF VELOCITY WITH TIME.

free fall

IS AN OBJECT THAT IS FALLING UNDER THE SOLE INFLUENCE OF GRAVITY. ANY OBJECT THAT IS BEING ACTED UPON ONLY BY THE FORCE OF GRAVITY IS SAID TO BE IN A STATE OF FREE FALL.
