Newton's Laws and Motion Review

This set of flashcards covers key terms and concepts from Newton's laws of motion, including definitions of friction, force, acceleration, and related equations.

Newton’s Second Law of Motion

The law stating that force equals mass times acceleration (F = ma).

Acceleration

A change in an object’s velocity, which can be an increase or decrease in speed or direction.

Net Force

The sum of all forces acting on an object.

Force

A push or pull on an object that may cause it to change its velocity.

Static Friction

The force between an object at rest and the surface it is on.

Sliding Friction

The force created when solid surfaces slide over each other.

Fluid Friction

The resistance encountered by objects moving through a fluid or gas.

Rolling Friction

The force created when objects roll over a surface.

Surface Area and Air Resistance

Increasing the surface area of an object decreases its speed due to increased air resistance.

Mass

The amount of matter in an object, which affects how much force is needed to move it.

Velocity

An object’s speed in a specific direction.

Friction

A force that opposes the motion of an object.

Speed

The distance an object travels over a certain period of time.

Equations for Force, Mass, and Acceleration

F = ma, m = F/a, a = F/m.

Distance

The total path traveled by an object.

Time

The duration of travel or movement of an object.

Direction of Force

The way in which a force is applied to an object, determining how the object moves.

Balanced Forces

Forces that cancel each other out, resulting in no movement.
