Newton's Laws of Motion

Flashcards on Newton's Laws of Motion, covering the three laws, related concepts, and key terms.

Newton's Laws of Motion

Three physical laws that together, laid the foundation for classical mechanics (study of the motion of bodies)

Isaac Newton

Mathematician, physicist, astronomer, theologian who developed the laws of motion

Force

A vector quantity (has magnitude and direction)

Motion

Is the change in position of an object with respect to its surrounding in a given time interval.

Balanced Force

Do not change the object's motion

Normal Force

An upward force that acts perpendicular to the surface in contact

Gravitational Force

A downward force that is equal to the weight of the object.

First Law: Law of Inertia

States that a body at rest will stay at rest and a body in motion will remain in motion unless it is acted upon by an external force.

Inertia

Property of an object to resist change

Second Law: Law of Acceleration

States that acceleration is directly proportional to the magnitude of a net force, and it follows the direction of the net force.

Third Law: Law of Interaction

States that for every action, there is an equal and opposite reaction.

The formula for the Second Law of Motion

F = ma

An object with greater MASS has greater

Inertia

A person pushes a box with a mass of 10 kg, causing it to accelerate at 2 m/s².
What is the force applied to the box?

A car has a mass of 1,200 kg. If the engine produces a forward force of 3,600 N, what is the car's acceleration?

An object experiences an acceleration of 5 m/s² when a 25 N force is applied. What is the mass of the object?
