(21 cards)

Inertia

Front

Tendency of an object to maintain its state of rest or uniform motion. The objects want to stay the way it is.

Back

Newton (N)

Front

1 kg*m/s^2

Back

Mass

Front

A measure of an objects inertia.

Back

Tension

Front

Pulling force, for ex: the force a cord exerts on a box when pulling it due to its elastic properties.

Back

Force Diagram

Front

A useless vocab word. A diagram depicting all forces on an object. Also called free-body diagram.

Back

Newton's First Law of Motion

Front

"Every object continues in its state of rest, or of uniform in a straight line, as long as no net force acts on it." An object in motion stays in motion due to inertia.

Back

Inertial Reference Frames

Front

Reference frames in which Newton's first law holds.

Back

Newton's Third Law of Motion

Front

Every force exerted has an equal and opposite force.

Back

Gravity on Earth

Front

9.8m/s^2

Back

Dynamics

Front

The connection between force and motion. Why objects move the way they do.

Back

Static Friction

Front

Friction of an object that is at rest. For ex: keeps a desk from sliding when little kids try to push.

Back

Newton's Second Law of Motion

Front

F = MA. Acceleration is directly proportional to the net force and inversely proportional to its mass. Direction of acceleration is the direction of the net force.

Back

Weight (Gravitational Force)

Front

Weight = Gravity * Mass

Back

Contact Force

Front

Force that occurs when two objects are in contact.

Back

Force

Front

Any kind of push/pull on an object. Vector.

Back

Net force

Front

ΣF (Sum of all forces on said object)

Back

Noninertial Reference Frames

Front

Reference frames in which inertia (Newton's first law) does not hold.

Back

Law of Inertia

Front

Newton's first law.

Back

Normal Force

Front

Perpendicular contact force. (What prevents you from falling through Earth.)

Back

Kilogram

Front

SI unit of mass.

Back

Kinetic Friction

Front

"Sliding friction" is opposite of the force acceleration. Ff = µ Fn
