This standard SI unit is used to measure acceleration.
What is meters per second squared (m/s2)?
The length of a vector arrow visually represents this property of the vector.
What is its magnitude (or size)?
If a vector points purely along the positive y-axis, its horizontal x-component equals this value.
What is zero?
Near the surface of the Earth, ignoring air resistance, all falling objects experience this constant downward acceleration value.
What is 9.8m/s2(gravity)?
Unlike a vector quantity, this type of physical quantity has magnitude but no direction.
What is a scalar?
A car travels exactly once around a 400-meter circular track and returns to its starting point; this quantity equals zero.
What is displacement (or average velocity)?
An automobile speedometer measures this specific type of speed at an exact instant, rather than an average over a whole trip.
What is instantaneous speed?
A ball is thrown straight up into the air. At its very highest point, this kinematic quantity is momentarily zero.
What is velocity (or speed)?
A ball is thrown straight up. At its highest point, its acceleration points in this direction.
What is downward (toward the ground)?
When adding two perpendicular displacement vectors, this classic geometric theorem is used to find the magnitude of the resultant
What is the Pythagorean theorem?
A ball is thrown straight up. At its highest point, its acceleration points in this direction.
What is downward (toward the ground)?
A heavy bowling ball and a light tennis ball are dropped from the same height in a complete vacuum; this ball lands first.
What is neither (they hit at the exact same time)?
multiplying velocity by time yields a quantity with the dimension of this measurement.
What is displacement/distance?
If Vector A points North with a magnitude of 10 and Vector B points South with a magnitude of 6, their resultant vector points in this direction.
What is North?
A ball is dropped from a cliff while an identical ball is thrown straight down from the exact same height 1.0 second later. As both balls fall, the distance between them does this over time.
What is increases (or gets farther apart)?
A car travels around a circular track at a constant speed of 25 m/s. Even though its speed never changes, the car is still accelerating because this property of its velocity vector is constantly changing.
What is its direction?
A hiker walks 3 meters north, then 4 meters east. The magnitude of their total displacement is this value.
What is five meters?
At the exact peak of a launched projectile’s trajectory, this is the angle between its velocity vector and its acceleration vector.
What is 90 degrees (or perpendicular)?
Ball A is dropped from a height h. Ball B is thrown straight upward with initial speed v0, reaches its peak, and falls back down. As Ball B passes its original launch height on the way down, the relationship between its acceleration and Ball A's acceleration is this.
What is they are equal (the same)?
