Force Notes from Research Presentations

A set of flashcards covering the concepts of various forces, including gravity, normal force, friction, tension, buoyancy, lift, and magnetic force.

Gravity

The force that attracts a body towards the center of another object, dependent on the mass of the objects.

Weight

A measure of the force of gravity acting on an object.

Normal Force

The perpendicular force that a surface exerts on an object pressing on it, acting opposite to the object's weight.

Contact Force (Applied Force)

A force transmitted through direct contact between objects, capable of acting in any direction.

Friction

A force that resists motion, acting opposite to the direction of an object's movement.

Rolling Friction

A type of friction encountered when an object rolls over a surface, such as a skateboard.

Sliding Friction

The resistance encountered when two surfaces slide against each other, exemplified by sliding in socks across a floor.

Fluid Friction

Friction experienced by an object moving through a fluid, best illustrated by air resistance.

Static Friction

The friction that exists between two objects that are not in motion relative to each other.

Tension

A pulling force that acts in a rope, string, or other object, creating extension.

Compression

The force that pushes things together.

Extension

The force that pulls things apart.

Spring

A force created by coiled material that can be compressed, stretched, or twisted.

Buoyant Force

The upward force a fluid exerts on a submerged object, acting opposite to the object's weight.

Archimedes' Principle

States that the buoyant force is equal to the weight of the fluid displaced by an object.

Lift

The upward force created when a solid object moves through a fluid, resulting from pressure differences.

Bernoulli's Principle

Describes the relationship between the speed of a fluid and the pressure it exerts.

Magnetic Force

The force that acts between positive and negative charges, causing like charges to repel and opposite charges to attract.
