Question | Answer |
---|---|
Force | A push or pull, or any action that involves the interaction of objects and has the ability to change motion. |
Newton | The metric unit of force equal to the force needed to make 1 kg object accelerate at 1 m/s/s. |
Tension | A pulling force that acts in a rope, string or other object. |
Extension | A "stretch" or increase in size. |
Compression | A "squeeze" or decrease in size. |
Friction | A force that resists the motion. |
Sliding friction | The friction force that resists the motion of an object moving across a surface. |
Static friction | The friction force that resists the motion between two surfaces that are not moving. |
Net force | The sum of all forces acting on an object. |
Balanced forces | Combined forces that result in a zero net force on an object. |
Equilibrium | The state in which the net force on an objects is zero. |
Normal force | The perpendicular force that a surface exerts on an object that is pressing on it. |
