Force and Motion

You are riding along in a car with Ms. Dollins when she suddenly slams on the brakes. Your body keeps moving forward because of

• inertia

• Mr. Dollins' deplorable driving

• you forgot to use a seatbelt

• acceleration

"For every action, there is an equal and opposite reaction."

• Newton's 1st Law
• Newton's 2nd Law
