force push or pull.
friction force that acts to oppose sliding between two surfaces that are touching.
net force combination of all forces acting on an object.
newton's first law of motion first law of motion: a body remains at rest or in motion with a constant velocity unless acted upon by an external force
newton's second law of motion second law of motion: the rate of change of momentum is proportional to the imposed force and goes in the direction of the force
newton's third law of motion third law of motion: action and reaction are equal and opposite
unbalanced forces In physics, tension is the pulling force exerted by a string, cable, chain, or similar solid object on another object
weight gravitational force between an object and earth.
