Cliff Notes I. Newton's 2nd Law A. acceleration ~ force (as you increase force, you increase acceleration) acceleration ~ 1/mass (as you decrease mass, you increase acceleration) a ~ F/m --> a = F/m II. Examples Ex1: A shopping cart is
pushed by a little girl. The acceleration of the shopping cart is
4 m/s2. The shopping cart is empty and has a mass of 1 kg. What
force did the girl push the cart with? 4 N Ex2: The girl decides to buy lots of ice cream. The mass of the cart increases, and it now has a mass of 5 kg. If the girl pushes the cart with a force of 10 N, what
is the acceleration? 2 m/s2 Attachments Newton's 2nd Law Practice - Practice problems for learning Newton's 2nd Law |
