Forces & MotionResultant force determines acceleration. Stopping Distance = Thinking + Braking.

Momentum is conserved.$\text{Speed} = \text{Distance} / \text{Time}$ $$F = m a$$ (Force = mass $\times$ acceleration)

$p = m v$ (Momentum = mass $\times$ velocity) $W = F s$ (Work Done = Force $\times$ distance)

$E_k = \frac{1}{2} m v^2$ (Kinetic Energy)Velocity-Time Graphs: Gradient is acceleration.

Area under graph is distance traveled. Momentum: Force is the rate of change of momentum: $F

= \Delta p / t$. Braking: $F s = \frac{1}{2} m v^2$. Uniform Acceleration: $v^2 - u^2 = 2 a

s$.2. WavesWaves transfer energy, not matter. Transverse (light,
