Motion Equations Quiz

Displacement and Acceleration

• Unit of displacement is typically measured in meters (m).
• Acceleration is often expressed in meters per second squared (m/s²).

Fundamental Formulas

• The formula for displacement can vary, but commonly, it's represented as ( s = ut + \frac{1}{2}at^2 ) where ( u ) is initial velocity, ( a ) is acceleration, and ( t ) is time.
• Gravitational acceleration is denoted by ( g ) and its approximate value is ( 9.81 , m/s² ).

Impulse and Momentum

• The unit of impulse is Newton-seconds (N·s) or equivalently, kg·m/s.
• Momentum (p) can be calculated using the formula ( p = mv ) where ( m ) is mass and ( v ) is velocity.

Special Terms and Concepts

• 'S.H.M.' stands for Simple Harmonic Motion, indicating periodic oscillations in physics.
• Escape velocity (( V_e )) is calculated with the formula ( V_e = \sqrt{\frac{2GM}{r}} ), where ( G ) is the gravitational constant, ( M ) is the mass of the celestial body, and ( r ) is the radius.

Torque and Measurement Systems

• Torque (τ) is measured in Newton-meters (N·m).
• 'C.G.S.' stands for Centimeter-Gram-Second, a system of units in physics.

Specific Vehicles and Machines

• 'Polar Satellite Launch Vehicle (PSLV)' refers to an Indian launch vehicle designed to place satellites in polar orbits.
• 'M.A.' stands for Mechanical Advantage, a measure of the force amplification achieved by using a tool or machine.

Energy and Motion

• The formula for potential energy (P) is given by ( P = mgh ), where ( m ) is mass, ( g ) is gravitational acceleration, and ( h ) is height.
• 'Ve' typically refers to escape velocity, the minimum speed required for an object to break free from a gravitational field.
