what 3 forces can slow you down when your riding a bike? | friction, air resistance, and gravity |
universal law of gravitation | gravity depends on mass and distance |
newtons 1st law(law of inertia) | a body in motion will stay in motion until a net force acts on it and a body at rest will stay at rest until a net force acts on it. |
friction | force between surfaces that poopses motion |
force | push or pull- measured in Newtons(N) |
static friction | force is applied but the objest doesnt move. |
rolling friction | has wheels |
liquid friction | has to do with water |
lubricants | reduces friction |
