Speed
This is the standard unit used to measure speed
What is meters per second (m/s)?
Unlike speed, velocity is this type of quantity because it includes a specific direction.
What is a vector quantity?
Acceleration is scientifically defined as the rate of change of this specific quantity.
What is velocity?
This type of speed is what a car’s speedometer displays at any given moment.
What is instantaneous speed?
This is the straight-line distance and direction from a starting point to an ending point.
What is displacement?
This is the standard unit used to measure acceleration.
What is meters per second squared (m/s²)?
To calculate this specific type of speed, you divide the total distance traveled by the total time taken.
What is average speed?
Two cars traveling at 60 mph on the same highway have different velocities if they are doing this. What is moving in opposite (or different) directions?
What is moving in opposite (or different) directions?
When an object slows down, it experiences this type of acceleration, which is mathematically represented as negative.
What is deceleration (or negative acceleration)?
If a runner completes a 400-meter track in 50 seconds, this is their average speed.
What is 8 meters per second? (400m / 50s)
An object moving at a constant speed must change its velocity if it moves along this type of geometric path.
What is a circular (or curved) path?
An object is accelerating if it changes its speed, its direction, or both.
What is both speed and direction?
On a distance-time graph, this visual property of the plotted line represents the object's speed.
What is the slope?
A cruise ship travels 60 kilometers North and then 20 kilometers South in 2 hours. This is its average velocity.
What is 20 kilometers per second North?
A sports car accelerates from rest to 30 m/s in exactly 5 seconds. This is its average acceleration.
What is 6 meters per second squared (6 m/s²)?
