How fast?
This type of acceleration occurs when an object slows down.
What is negative acceleration (or deceleration)?
The unit of pressure in the SI system.
What is pascal (Pa)?
Energy in motion is called this.
What is kinetic energy?
This force keeps the planets in orbit around the sun.
What is gravity?
This Pixar movie involves a robot cleaning up Earth and escaping gravity.
What is WALL-E?
The area under a velocity-time graph gives you this.
What is displacement?
This formula calculates pressure.
What is pressure = force ÷ area?
Energy stored due to position or height.
What is potential energy?
The Earth’s gravity gives objects this acceleration (in m/s²).
What is 9.8 m/s²?
This Pink Floyd album is named after an astronomical object.
What is The Dark Side of the Moon?
This equation: v = u + at connects velocity, acceleration, and this variable.
What is time?
This is why snowshoes prevent you from sinking in snow.
What is reduced pressure due to larger surface area?
The SI unit of energy.
What is the joule?
The bending of light as it passes through materials.
What is refraction?
In Avengers: Endgame, this concept is used to travel through time.
What is the quantum realm (or quantum physics)?
The unit for acceleration in the SI system.
What is m/s²?
The pressure in a fluid increases with this variable increasing.
What is depth?
The formula for gravitational potential energy.
What is PE = mgh?
This invisible form of energy travels as waves and allows us to see.
What is light (or electromagnetic radiation)?
This theoretical particle inspired a book called The God Particle.
What is the Higgs boson?
An object thrown upwards will have this value for velocity at the top of its path.
What is zero?
This principle explains why a balloon expands when air is pumped in.
What is Pascal's Principle?
A 2 kg object at 5 m height has how much potential energy? (g = 10 m/s²)
What is 100 J?
This phenomenon explains why we hear thunder after we see lightning.
What is the speed difference between light and sound?
This author of Contact helped popularize physics through fiction.
