Reduction in speed or negative acceleration
Friction or air resistance
F=m⋅ΔvΔtF = \frac{m \cdot \Delta v}{\Delta t}F=Δtm⋅Δv
Decelerating force in Newtons
Mass of the object in kilograms
Change in velocity in metres per second
Time over which deceleration happens in seconds
Heavier vehicles need more force to decelerate in same time
Faster vehicles need greater force to stop in given time
Reduce friction, making it harder to decelerate
Crucial for generating necessary decelerating force
Braking distance increases with speed
