Motion - correct answers change in position over change in time 4 types of motion - correct answers linear, circular, projectile, and rotational The two types of physical quantities - correct answers scalar quantities and vector quantities Scalar quantities - correct answers Only a magnitude with units IE: time, speed, distance, temperature Vector quantities - correct answers Magnitude AND direction IE: displacement, velocity, acceleration, force Magnitude of velocity - correct answers speed Given two vectors, A and B, what is A + B? - correct answers A + B = C What is the vector C called - correct answers A resultant vector How do you add vectors graphically? - correct answers Use the tail to tip method What is the acceleration - correct answers The limit as t approaches 0 of the change in velocity over the change in time Motion in one dimension - correct answers Motion along a straight line Displacement - correct answers Change in X = Xf - Xi and Y = Yf - Yi What is the difference between distance and displacement? - correct answers Distance doesn't care about direction Slope of a line in position vs time graph - correct answers velocity For uniform motion, acceleration is what? - correct answers Equal to zero In non-uniform motion, how is the instantaneous speed found? - correct answers The slope of a tangent line at the specified point. (The derivative of the velocity) If you are given Velocity vs Time, how do you find Position vs Time? - correct answers Take the integral Displacement on a graph is - correct answers The area under the curve If the sign of acceleration and velocity are the same, an object is... - correct answers speeding up If the sign of acceleration and velocity are opposite, an object is... - correct answers slowing down The components of vector A will be - correct answers Vector Ax and vector Ay Component Ax - correct answers is the length (magnitude) Component Ay - correct answers the angle of the vector
