While driving you hit the brakes and feel your body move forward before the seat belt stops you. Your body moving forward is an example of
a
friction
b
inertia
c
balanced forces
d
equilibrium
b
inertia
When you hit the brakes in a car, the car slows down due to the friction between the brakes and the wheels, but your body continues to move forward due to inertia. Inertia is the property of an object to resist changes in its state of motion. Your body wants to keep moving forward in a straight line at a constant speed because that was its motion before the car began to decelerate. The seat belt then exerts a force on your body to stop it from moving forward, which counters your body's inertia.
