What is the equation to find impulse? | Force x Time = Impulse |
What are the 2 equations for velocity? | Distance divided by time = Velocity, and acceleration due to gravity times time |
What is displacement? | The change in position |
What is constant velocity? | Where the velocity is the same. |
What is average velocity? | The total displacement, divided by the time taken. |
What is instantaneous velocity? | The velocity at one specific moment. |
What are the 2 equations to get acceleration? | The final velocity, minus the initial velocity divided by time, and force divided by mass. |
What is a force? | Anything with the ability to push or pull. |
An object at rest will stay at rest and an object in motion will continue in motion with the same velocity unless acted on by an outside force is... | Newton's first law. |
