PHYSICS FORMULA SHEETS FOR CLASS 9TH
Motion
Speed and Velocity
Average Speed
Average Velocity
Acceleration
Three equations of Motion
Where S is the displacement, u is the initial velocity and v is the final
velocity, a is the acceleration and t is time
Displacement in nth second
, Force and Laws of Motion
Momentum(P)
Where m is the mass of the object and v is the velocity
Newton’s second law
Here F is the force applied, v and u are the initial and final velocities
Impulse
Law of Conservation of Momentum
The law of conservation of momentum, states that
If the net external force on a system of particles is zero, the linear momentum of
the system remains constant
Here subscripts 1 and 2 correspond to the two objects and v and u are the
initial and final velocities of the respective objects
Centripetal Acceleration
Centripetal Force
