Force & Motion
by Chris Woodford. Last updated: November 5, 2017.
It's hard to believe, but everything in the world is in motion, all the time. Even things that look perfectly still are packed with atoms that are vibrating with energy. Understanding how motion works was one of the great milestones of science and it's credited to the brilliant English physicist Sir Isaac Newton. His laws of motion, written over 300 years ago, were so well stated that scientists still use them in most situations today. The basic idea Newton taught us is that motion is caused by forces—which is easy enough to understand: kick a ball (the force) and it flies into the air (the motion). But forces don't always make things move: a bridge has lots of forces acting on it, but it doesn't...Read More

direction - The way or course toward which something moves or faces
distance - the amount of space between things
electromagnetism - the combined force of electricity and magnetism
energy transfer - the movement of energy from one object to another or the change of energy from one form to another
force - the strength or energy that moves an object
friction - a force that slows down moving things
gravity - the force that pulls things toward the center of Earth or any other object that has mass
inertia - the tendency of an object to resist change in the direction or speed of its motion
kinetic energy - the energy that a moving body has because of its motion
magnetism - a force that pushes and pulls certain metals
mass - the amount of matter, measured on Earth by its weight
momentum - the strength or force that keeps something moving
motion - the act of going from one place to another; movement
potential energy - the energy a body has because of its position, electrical charge, or structure; stored energy
speed - the rate of movement
weight - how heavy something is, determined by the pull of gravity on the object's mass

Try to think of something that doesn't involve energy and you won't get very far. Even thinking—even thinking about energy!—needs some energy to make it happen. In fact, everything that happens in the world uses energy of one kind or another. But what exactly is energy?
Energy is a bit of a mystery. Most of the time we can't see it, yet it is everywhere around us. Revving car engines burn energy, hot cups of coffee hold energy, street lights that shine at night are using energy, sleeping dogs are using... Read more

Bill Nye the Science Guy: EnergyEnergy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.

Bill Nye the Science Guy: MotionIn physics, motion is a change in position of an object over time. Motion is described in terms of displacement, distance, velocity, acceleration, time and speed. ... Thus, everything in the universe can be considered to be moving.

Bill Nye the Science Guy: MomentumMomentum is a physics term; it refers to the quantity of motion that an object has. A sports team that is on the move has the momentum. If an object is in motion (on the move) then it has momentum. Momentum can be defined as "mass in motion." ... Momentumdepends upon the variables mass and velocity.
