The location of an object.

The rate of change of velocity.

An object in motion tends to stay in motion and an object at rest tends to stay at rest.

The force of attraction between objects due to their mass.

A lever with a fulcrum in the center that is found on a children's playground.

A fixed object used to determine if something is in motion.

A push or a pull.

The acceleration of an object depends on the mass of the object and the amount of force applied.

As distance between two objects increases, gravity does this.

The simple machine used to raise and lower a flag.

Speed=Distance/Time

A force such as friction. air resistance, or tension.

Force=mass x acceleration

As the mass of objects increase, gravity does this.

An electric fan and a bicycle are examples of this type of simple machine.

A quantity with both magnitude and direction.

Gravity, magnetism, or electricity.

Every force has an equal and opposite force.

When gravity pulls down an object and no other forces act on it.

A spiral staircase is an example of this simple machine.

Speed in a certain direction.

A force that causes a change in the object's motion.

The tendency for an object to resist a change in motion.

When an object travels around another object in space.

A knife and an axe are examples of this simple machine.
