Josh`s physics kinematics outline
... Objects that are shot through the air are called projectiles. Each projectile follows a certain trajectory. If you know the initial thrust that the object received, you can calculate the trajectory. To calculate the trajectory, you must break the vector of the projectile into its horizontal and vert ...

17.5 Acceleration and Newton`s 2nd law of motion
... About 100 years later, Newton’s second law explained why. A heavy object experiences a stronger pull from gravity than a light object, but it also has more inertia which makes it harder to get moving! The two effects cancel out, so all objects fall to Earth a = F1/m1 = F2/m2 with the same accelerati ...
