Answer 1

Answer:

• Force and Motion:-

$Average Speed = \frac{Total Distance}{Total Time}$

• Velocity:-

$Velocity = \frac{Displacement}{Time}$

• Acceleration:-

$Acceleration = \frac{Final Velocity- Initial Velocity}{Time for velocity change}$

• Momentum:-

Momentum = Mass × Velocity

• Conservation Of Momentum:-

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

• Kinetic Energy:-

Kinetic Energy = $\frac{1}{2}$ mass × velocity²

• Density:-

$Density = \frac{mass}{volume}$
