Speed
The calculation for speed.
What is Distance / Time
When a car is not moving and its graph has a horizontal/flat line.
What is Rest or Zero?
The horizontal line tells us this about the object's motion
What is zero acceleration?
___________ is how far an object moves in total.
___________ is how far an object is from its starting point.
Distance and Displacement
The largest desert in the world.
What is the Antarctic?
The speed of an object if the distance is 70 meters and the time is 10 seconds including units.
What is 7 m/s?
A graph with a positive and straight line represents the following kind of speed. Accelerating, Constant, Decelerating, Rest
What is Constant?
If a speed time graph has a flat line it tells us what two things about the objects motion?
What is the speed is completely constant or there is no speed/motion?
Something that has speed with a specific direction.
The only continent that is located in all four hemispheres.
What is Africa?
The playground is 80 meters away and you get there 40 seconds after leaving class. This will be your average speed.
What is 2 m/s
What does the steepness (slope) of the line tell us about the object's motion? "The steeper the line the..."
What is the steeper the line, the faster the object is moving?
What the slope of a speed-time graph tells us.
What is acceleration?
What a cops speed gun would read.
What is instant or instantaneous speed?
The number of dimensions that the world around us is composed of. Bonus points for naming them all.
What is 4? Length, Width, Depth, and Time
It takes me 6 hours to drive to Nashville, TN. My route is 300 miles long. This is my average speed in mph.
What is 50 miles per hour
Given that the car goes from only 10m/s and speeds up to 20m/s over the course of 5 seconds, it has the following acceleration?
What is 2m/s^2
What the slope tells us about the object's motion.
What is deceleration?
Something that has both a magnitude and a direction to it.
What is a vector?
What is sound?
How far a dog can walk if its speed is 30 m/s and it travels for 700 seconds.
What is 21,000 meters?
What is that the object is positively accelerating or speeding up?
What the steepness (slope) of a line indicate. "The steeper the line, the..."
What is the steeper the line, the faster the acceleration?
The measurement of the TOTAL distance and object travels over the TOTAL time it takes to travel that distance
What is average speed?
How many known moons does Jupiter have?
