definition of force a push or pull. when one object pushes or pulls another object the first object exerts a force on the second object
definition of friction the force that 2 surfaces exert on each other when hey rub against eachother
definition or mass the amount of matter in an object
definition of weight the force of gravity acting on an object
state the law of universal gravitation the force of gravity between all objects in the universe have mass
definition of gravity a force that pulls objects towards eachother
what happens when 2 forces are in the same direction the object they're putting the force on will move in the same direction as the force
how does mass affect inertia the greater the mass of an object the greater its inertia and the greater force required to change its motion
what is newtons first law of motion. example an object a t rest will stay at rest an object in motion unless acted upon by an nonzero force will stay in motion unless acted upon by an nonzero net force. a falling book hits the floor
what is newtons second law of motion. example an objects acceleration depends on its mass and net force acting on it. pushing full shopping carst vs. empty shopping cart.
what is newtons third law of motion. example if one object exerts a force on another object then the second object exerts a force of equal strength in the opposite dirrection of the first. laying in bed
how does mass affect gravity the more mass the greater the gravitational force between it and other objects
what is net force the combination of all the forces on an object
