| Question | Answer |
|---|---|
| Newton's First law of motion | An object at rest or moving at a constant speed in a straight path will continue to do so until a net force acts on it |
| Newton's second law of motion | An object acted upon by a net force will accelerate in the direction of the force according to the equation |
| Force | A push or pull |
| Unbalanced force | The net force on an object are not zero |
| Normal force | The outward force from a surface |
| Force | A push or pull |
| Net force | The total force felt by a object |
| Newton's third law of motion | Force always act in equal but opposite pairs |
| Balanced force | Two or more forces whose effects cancel each other |
| Friction | the rubbing force that acts against motion between two touching surfaces |
| An object will __________ when the net force is not zero | Accelerate |
| ____________ will never speed up an object | Friction |
| The friction that prevents an object from moving when a force is applied is ____________ friction | Static |
| The friction that slows down an object that slides is _________ friction | Sliding |
| A ________ helps reduce sliding friction | Brake |
| Normal force is supplied by the __________ of the surface | Slipping |
