Language of Motion
This is the measurement of how far an object has traveled from its starting point.
What is Distance?
Newton's First Law is also known as the Law of this—which means objects are lazy and want to keep doing whatever they are already doing.
What is Inertia?
This is the type of energy an object has because it is currently moving.
What is Kinetic Energy?
A seesaw at the playground is a perfect example of this simple machine that rests on a pivot point called a fulcrum.
What is a Lever?
This is the name for the very highest point, or the peak, of a wave.
What is the Crest?
This tells you how fast an object is moving and is calculated by the equation s = d/t.
What is Speed?
In physics, this is the simple word for any push or pull on an object.
What is a Force?
This is "stored" energy an object has because of its position, like a roller coaster waiting at the top of a hill.
What is Potential Energy?
This simple machine is just a flat surface tilted at an angle, making it easier to push heavy things up instead of lifting them.
What is an Inclined Plane?
This is the name for the very lowest point, or the valley, of a wave.
What is the Trough?
This is just like speed, but it also tells you the exact direction the object is going (like "50 mph North").
What is Velocity?
Newton's Second Law is represented by this famous math equation showing how force, mass, and acceleration are connected.
What is F = ma?
The Law of Conservation of Energy states that energy cannot be destroyed, and it cannot be this.
What is Created?
This simple machine has a grooved wheel and a rope, and it makes lifting heavy buckets much easier.
What is a Pulley?
This is the distance measured from one wave crest directly to the next wave crest.
What is Wavelength?
If you run exactly one lap around a 400-meter track and stop exactly where you started, your distance is 400 meters, but this measurement is zero.
What is Displacement?
If you push a bowling ball and a tennis ball with the exact same amount of force, the tennis ball will accelerate faster because it has less of this.
What is Mass?
As a roller coaster crests the top of a hill and starts rushing downward, this type of energy is actively being converted into kinetic energy.
What is Gravitational Potential Energy?
While a simple machine like a ramp reduces the amount of force you need to lift a heavy box, the trade-off is that it requires you to apply that force over a longer one of these.
What is Distance?
If a wave's speed stays exactly the same, increasing its frequency will automatically cause this measurement to decrease.
What is Wavelength?
If a car is driving at a constant speed of 60 mph in a perfect circle, it is technically doing this because its direction keeps changing.
What is Accelerating?
When a bug splatters on a moving car's windshield, the car hits the bug with a lot of force. According to Newton's Third Law, the force the bug exerts on the car is this.
What is Exactly the Same? (or Equal)
If you push against a solid brick wall with 100 Newtons of force until you are exhausted, but the wall does not move a single inch, you have done exactly this much Work in a physics sense.
What is Zero?
A wheelbarrow is an example of a Class 2 lever. You apply the lifting force at the handles, the heavy load sits in the bucket in the middle, and this specific part acts as the fulcrum.
What is the Wheel?
You can see the light from a massive star exploding in outer space, but you would not hear it because sound waves require this to travel.
What is a Medium? (or Matter/Particles)
