Motion and Types of Motion

These flashcards cover fundamental concepts of motion, types of motion, speed, velocity, and acceleration as discussed in the lecture notes.

Motion is defined as the movement of an object from one __________ to another reference point.

reference point (origin) to destination.

Distance is the __________ path travelled by the object.

actual

Distance is a __________ quantity that describes the magnitude of movement without direction.

scalar

The SI unit of distance is __________.

Metre

Displacement is the __________ distance between the initial and final points.

shortest

Displacement is a __________ quantity as it has both magnitude and direction.

vector

The SI unit of displacement is __________.

Metre

Distance is either equal to or greater than __________.

displacement

In straight motion, the object moves in a __________ linear path.

straight

The motion where an object circulates around a fixed point is called __________ Motion.

Circular

In rotatory motion, particles of the body describe concentric __________ about the axis of motion.

circles

Vibratory motion is when particles move and rotate about a __________ point.

fixed

Uniform motion occurs when a body covers __________ distance in equal intervals of time.

equal

Non-uniform motion occurs when a body covers __________ distance in equal intervals of time.

unequal

Speed is referred to as the rate of __________ of an object.

motion

The formula for speed is __________.

Speed = Distance / Time.

Average speed is calculated as the total distance covered divided by the __________ taken to cover the distance.

total time

Instantaneous speed is the speed of an object at __________ point in time.

any

Velocity is defined as the amount by which an object is __________ in a unit time interval.

displaced

The SI unit of velocity is __________.

m/sec

When an object covers equal distance in equal time intervals, it is said to have __________ velocity.

uniform

Average velocity can be obtained by taking the arithmetic mean of the __________ velocity and final velocity.

initial

The rate of change of velocity is called __________.

Acceleration

Acceleration is calculated using the formula: __________.

a = Δv / Δt

The unit of acceleration is __________.

m/sec².

Velocity can be positive, negative, or __________.

zero.
