In physics, acceleration is defined as the rate of change of velocity with respect to time. Finding the dimensional formula of acceleration is a fundamental concept in Class 11 physics mechanics.
The SI unit of acceleration is meters per second squared (m/s²).
Because mass is not involved in kinematics, 'M' has a power of 0.
Acceleration is a vector quantity.
The dimensional formula of acceleration is written as:
Where:
Acceleration = Velocity ÷ Time
Since Force = Mass × Acceleration, its dimensional formula is [M1 L1 T-2].
A Biker Rides 700m North then 300m East — Find Displacement
A biker rides 700m north then 300m east. Displacement = 100√58 m ≈ 761.6 m at 23.2° east of north. Distance = 1000 m. Step-by-step vector solution.
A Body at Rest May Have — What Properties Are Possible?
A body at rest may have potential energy and acceleration. It has zero velocity, zero momentum, and zero kinetic energy. It cannot have velocity or momentum.

A Cabin is Moved Up the Inclined Plane — Work, Force, and Energy
When a cabin is moved up an inclined plane, the force required is mg sinθ + friction force, and work done equals force × displacement along the incline.
