Motion
This can either be a stationary or moving object used to determine another object's motion.
What is a reference point?
These two variables are needed to calculate speed.
What are time and distance?
What is change in speed divided by change in time?
This is the independent variable on speed and acceleration graphs.
What is time?
A negative slope indicates an object returning to "start" on both a speed and an acceleration graph.
What is false?
This is the most commonly used reference point.
What is the surface of the Earth?
This is the formula to calculate time if speed is known.
What is distance divided by speed?
This variable is often a squared value in a unit of acceleration.
What is the time variable?
These are the y-axes on speed and acceleration graphs respectively.
What are distance and speed?
This symbol is used to represent "change" in physics and chemistry equations.
This is a measure of how fast an object is moving.
What is speed?
This is the speed of an object that traveled 40 km in 80 seconds.
What is 0.5km/s?
What is a straight line with a negative slope?
A horizontal line on a speed graph represents this type of motion.
This shape of graph represents acceleration on a distance vs time graph and increasing acceleration on a speed vs. time graph.
What is a curved line with a positive slope.
This is how to determine the speed of an object's motion.
What is the distance it travels in a period of time?
This term is speed in a specific direction.
What is velocity?
This can indicate rapid acceleration or deceleration on a speed vs. time graph.
What is a steep slope?
You cannot determine the direction of an object's motion from an acceleration graph.
What is true?
These types of lines represent a non-moving object on a speed and acceleration graphs respectively.
What are a horizontal line anywhere and a horizontal line on the x-axis?
What is constant acceleration?
This variable is constant if an object has no speed.
What is distance?
This variable is constant on an acceleration graph when the object does not accelerate or decelerate.
What is speed?
This is the description of an object's motion on a speed graph when a curved line that gets gradually more horizontal has a negative slope.
What is an object returning to the starting point with a decreasing speed?
This is the average rate of acceleration when an object increases in speed between 20 and 55 seconds from 25 to 95 km/hour.
What is 2 km /hour x second?
