# Physics I - Exam(1)

### Chapters 1 - 4

What is the unit of measurement for time? Second
What is the unit of measurement for energy? Joule
What is the unit of measurement for mass? Kilogram
What is the unit of measurement for acceleration? Meters per second squared
What is the unit of measurement for impulse? Kilograms meters per second
What is the unit of measurement for velocity? Meters per second
What is the unit of measurement for distance? Meter
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.
What is inertia? The property of an object that resists change of motion.
What is the unit of measurement for force? Newton
What is net force? The total of all forces acting on an object.
What is free fall? Acceleration due to the force of gravity.
What is the acceleration due to gravity on Earth? 9.8 m/s^2
