What are balanced forces? | Equal forces acting in opposite directions. |
What are unbalanced forces? | Unequal forces in opposite directions. |
What is net force? | Sum of all forces acting on an object. |
What is average speed? | Total distance divided by total time. |
What is sliding friction? | Force that acts in the opposite direction to the motion of a surface sliding on another surface |
What is speed? | Distance divided by time. |
What is a force? | A push or pull exerted on a body or object. |
What is displacement? | Distance and direction of an object from its starting point. |
What is friction? | Force that opposes the sliding motion of 2 surfaces in contact. |
What is air resistance? | Force that opposes the motion of objects that move through the air. |
What is velocity? | Vector speed and direction of motion. |
What is instantaneous speed? | Speed of an object at a specific point in time. |
What is acceleration? | The change in velocity divided by the time for the change to occur. |
What is the difference between distance and displacement? | Displacement involves distance and direction. |
What is the difference between speed and velocity? | Speed is distance over time and velocity is speed and direction. |
What is positive acceleration? | Speeding up. |
What is negative acceleration? | Slowing down. |
What is the difference between positive and negative acceleration? | Positive acceleration is speeding up and negative acceleration is slowing down. |
How are force and motion related? | They both involve movement. |
What causes friction? | The sliding motion opposed with objects in contact. |
