Science 10 – Physics Unit Review

Exam Date: JANUARY 16TH, 2017

UNIFORM MOTION

← Define displacement (change in position, Δx), time interval (Δt), and  velocity (vav) 

← Explain the difference between displacement (change in position) and distance

← Explain what a time interval is and calculate it

← Explain what a change in position is and calculate it

← Explain what average velocity is and calculate it using vav = ∆d/∆t

← Describe the common units for velocity, time and displacement

← Take data and plot a position-time graph and draw a line of best fit

← Explain the difference between directional motion (vector) and magnitude (size/amount)

← Explain the difference between “Vector” and “Scalar” quantities and give examples of each

← Read and explain the information found on a position-time graph

(ie. positive, negative and zero slope and the motion and direction described)

← Explain the difference between speed and velocity

← Calculate average velocity by finding the slope of a position-time graph

← Calculate average velocity over multiple sections of a position-time graph

← Calculate average velocity over multiples sections in a word problem where the object is moving at two different velocities

← Solve for each variable when using the vav = ∆d/∆t

TERMS TO KNOW:

|Displacement |Positive slope |

|Distance |Negative slope |

|Position |Zero Slope |

|Position-time graph |X-axis |

|Scalar |Y-axis |

|Vector |Average velocity |

|Uniform Motion |Speed |

| | |

(…see over for “accelerated motion”…)

ACCELERATED MOTION

← Explain what acceleration is in terms of changes in velocity [positive= speeding up, negative=slowing down, constant=zero]

← Give more than one real-life example of positive acceleration, negative acceleration, and constant acceleration

← Explain positive and negative motion using a frame of reference. (example: north is positive, south is negative)

← Determine ∆v (change in velocity) by using vf - vi

← Use the acceleration formula (a = ∆v/∆t) to determine acceleration for different data sets and given information

← Plot a velocity-time graph and explain the motion demonstrated by the graph

← Determine the slope (acceleration)

← Explain what the slope is telling us [positive = increasing constant acceleration, negative =decreasing constant acceleration, zero = constant speed]

TERMS TO KNOW:

|Acceleration |Average Acceleration |

|Change in Velocity |Constant Acceleration |

|Deceleration | |

|Constant Velocity |Velocity-time graph |

← If you have any questions, please see me in FLEX before the test day.

(GOOD LUCK!!
