Balanced vs Unbalanced forces and the 6 types of forces

Gravitational Force

The force of gravity pulling towards the center of a planet or massive object.

Normal Force

The force between two surfaces in contact, always perpendicular to the surfaces.

Friction Force

The force that opposes the motion or potential motion when two surfaces try to slide across each other.

Tension Force

The force present in ropes, strings, or wires pulled taut, acting along the length of the rope.

Spring Force

The force that exists when a spring is deformed from its resting length, either stretched or compressed.

Drag Force

Also known as air resistance, it opposes the motion of an object moving quickly through the air.

Contact Force

A force that requires two objects to be touching.

Non-Contact Force

A force that does not require two objects to touch.

Balanced Force

When equal forces are applied to an object, canceling each other out.

Unbalanced Force

When unequal forces are applied to an object, causing a change in its motion.

Net Force

The combination of all forces acting on an object.

Weight

The measure of the pull of gravity on an object, which changes if gravity changes.

Mass

A measure of how much matter is in something, which does not change.

Net Force

Combination of all forces acting on an object.

Calculating Net Force (Same Direction)

Add the forces together when they are acting in the same direction.

Calculating Net Force (Opposite Direction)

Subtract the forces when they are acting in opposite directions.

Distance-Time Graphs

Graphs that show how far, how fast, and what direction an object traveled.

Steep Line on a Distance-Time Graph

Indicates the object is traveling the fastest.
