Force and newtons
Term | Definition |
---|---|
Balanced forces | Forces are balanced when the forces pushing (or pulling) an object in one direction are the same size as the forces acting in the opposite direction. |
Force | strength or energy as an attribute of physical action or movement. |
Net Force | In physics, net force is the overall force acting on an object. |
Newtons second law of motion | Heavy objects that need more force to go as the same speed. |
Unbalanced Forces | In physics, tension is the pulling force exerted by a string, cable, chain, or similar solid object on another object. |
Center of mass | A point representing the mean position of the matter in a body or system. |
Friction | The resistance that one surface or object encounters when moving over another. |
Newtons first law of motion | States that if the net force acting on an object is zero, the object will remain at rest or move in a straight line with the constant speed. |
Newtons third law of motion | States that forces always act in equal but opposite pairs. |
Weight | Gravitational force between an object and earth. |
