Physics

It is defined as the science that deals with matter and energy and their interactions.

Matter

It is simply defined as anything that occupies space and has mass.

Energy

It is defined as the capacity of doing work.

Accuracy

It refers to the closeness of a measurement to the accepted value for a specific physical quantity.

Precision

It is the agreement among several measurements that have been made in the same way or it is the closeness of measured values to each other.

Random Error

This type of error occurs when there are variations in the environment or measurement technique.

Systematic Error

This type of error is caused by faulty instruments or the incorrect handling of instruments or incorrect calibration of measuring instruments.

Scalar

Quantities that can be associated with the magnitude only.

Vector

Quantities that can be associated with  both magnitude and direction.

Geometrical Method

Vectors may be added graphically or analytically. The graphical method, which is also known as ______, requires no computation.

Resultant

Addition of vectors is equivalent to composition of vectors, and the sum of vectors is called the ______ of vectors.

Position Vector

Starting from the origin to the point where the particle is.

Velocity Vector

Time derivative of the corresponding component of the position vector.

Acceleration Vector

Derivative of the x-component of the velocity vector as a function of time.

Mechanics

Forces acting on bodies.

Kinematics

Motion of a body.

Dynamics

Relates force and motion.

Displacement

It refers to the change of position of an object. It is described by its magnitude and direction; hence, it is a vector quantity.

Displacement

Difference between final position to initial position.

Meter

The SI unit for displacement is ______.

Distance

The absolute value of displacement is called ______.

Average Velocity

It is the displacement divided by the time of travel.

Speed

The absolute value of velocity is called ______.

Instantaneous Velocity

It is the velocity at a specific instant of time or specific point along the path.

Acceleration

It is the rate at which velocity changes.

Instantaneous Acceleration

It is the acceleration at a specific instant of time.

Average Velocity

Rate at which an object changes in position from one place to another.

Instantaneous Velocity

Rate at which an object changes its position from one place to another.

Translation

It is the term used in physics for motion in a straight line.

Position

The location of an object with respect to a frame of reference.

Projectile

It is a body which is given an initial velocity and then allowed to move under the influence of gravity only.

Trajectory

Once a projectile is released, it will trace a curvilinear (non-linear) path called ______.

Projectile Motion

It is a combination of horizontal motion with constant velocity and vertical motion with constant acceleration.

Free Fall

Motion under sole influence of a gravitational acceleration.

Circular Motion

An object that moves in a circle at constant speed v is said to be experiencing a uniform circular motion.

Angular Displacement

The angle in radians (degrees, revolutions) through which a point or line has been rotated in a specified sense about a specified axis.

Angular Velocity

It can be considered to be a vector quantity, with direction along the axis of rotation in the right-hand rule sense.
