Unformatted text preview: acceleration Forces-Forces change the motion of objects.-Momentum the (mass x velocity) of an object-Force Anything that can cause a change in an objects momentum Conservation of Momentum-Momentum = mass x velocity-Just like energy momentum is conserved in the absence of forces. The acceleration of Gravity Universal Law of Gravitation-Between every two objects there is an attractive force, the magnitude of which is directly proportional to the mass of each object and inversely proportional to the square of the distance between the centers of the objects.-F g = G M 1 M 2 /d 2 Universal Gravitation-Your weight is a measure of the force of gravity upon you.-You will weigh different amounts on different planets or moons.-Inertial mass same as gravitational mass; explained later by Einstein as curvature of space due to gravity....
