Ways newtons 1st law is used in your life
A ball is on the ground and it's kicked. Riding a bike and you hit a curb and are sent flying over the handlebars. A person driving a car at high speeds hits a wall and stays in the car because of their seatbelt. The wheel on wheel of fortune doesn't move until someone spins it. I go home from school and sit on the couch and don't move until I do my science homework.
