This invisible downward pull safely brings dropped bouncy balls back to Earth.
What is Gravity
How quick you move from one place to another, whether you are a slow snail or a zooming cheetah.
What is speed
The full space between two fixed points, like the run from your desk to the door.
What is distance
This shape is formed when two lines meet at a common point.
What is an angle
The letter "d" stands for this scalar length in motion equations.
what is distance
The upward aerodynamic force that acts at a 90-degree angle to oncoming airflow.
What is lift
This vector quantity tells us both an object's speed and its exact direction.
What is velocity
The vertical distance reached by an object relative to ground level.
What is height
Spreading your thumb and index finger flat makes an "L" shape, representing a 90-degree angle.
What is a right angle
The standard unit of measure for both speed and velocity.
What is m/s
If you drop a soft eraser from high above your desk, this force pulls it down.
What is Gravity
Speeding up, slowing down, or changing directions are all examples of this rate of change.
What is Acceleration
The scientific study of moving gases and how forces act on and flow around moving solid bodies.
What is aerodynamics
This type of angle is "sharp" and strictly smaller than 90 degrees.
What is an acute angle
Height is measured along this specific coordinate axis.
What is the y-coordinate axis
This standard scientific unit is used to measure both lift and gravity
What are Newtons
You calculate an object's speed by dividing its distance by this.
what is time
The branch of classical physics that describes how objects move, including calculating elapsed time and displacement.
What is kinematics
This type of angle is "big and wide" and strictly greater than 90 degrees.
What is an obtuse angle
The formula Δv/Δt is used to calculate this.
What is acceleration
Gravity accelerates all objects downward toward Earth's center at the same rate.
what is g = 9.8 m/s2
If a test drone covers 100 meters in 10 seconds flying due East, its velocity is exactly this.
what is 10 m/s east
Speed is a type of quantity: a rate that measures distance regardless of direction.
What is a scalar quantity
Lift acts perpendicular to the oncoming airflow, so it forms this specific geometric angle.
What is a right angle/ 90 degrees
Calculating velocity requires both distance and time (d/t), plus this extra piece of information.
What is direction or heading
