Types of motion

Key Notes :

Definition of Motion:

• Motion refers to the change in the position of an object over time relative to a reference point.

Types of Motion:

Translatory Motion:

• This occurs when all parts of an object move in the same direction and at the same speed.
• Example: A car moving straight on a road.

Rotatory Motion:

• When an object moves around a fixed point or axis, it is said to be in rotational motion.
• Example: The wheels of a bicycle, the Earth revolving around the Sun.

Vibratory Motion:

• This motion occurs when an object moves back and forth rapidly in a fixed position.
• Example: A vibrating guitar string, a swinging pendulum.

Other Types of Motion:

Periodic Motion:

• Motion that repeats itself at regular intervals of time.
• Example: The swinging of a pendulum, a clock’s hands moving.

Non-Periodic Motion:

• Motion that does not repeat itself in a regular pattern.
• Example: A car moving on a road with traffic or weather changes.

Uniform Motion:

• Motion in which an object covers equal distances in equal intervals of time.
• Example: A train moving at a constant speed.

Non-Uniform Motion:

• Motion in which the object does not cover equal distances in equal intervals of time.
• Example: A car speeding up or slowing down.

Important Terms:

• Speed: The rate at which an object moves (distance covered per unit of time).
• Velocity: Speed in a specific direction.
• Acceleration: The rate of change of velocity.
