SAFETY IN PUBLIC TRANSPORT AND FORCES AND TERMINAL VELOCITY

• when a vehicle travels at a steady speed in a straight line the resistive forces are balancing the driving force.
• stopping distance= thinking distance + braking distance
• If resultant force is zero, that means it moves at its terminal velocity.
• Parachutes are designed to increase the drag force on a parachutist so that the terminal velocity is reduced.
• streamlining reduces drag force on an object so that its maximum velocity is increased because it reduces surface area.
