Formula for Net Force

Front

F1+F2-F3=0

Back

Equilibrium

Front

When the sum of all forces acting on an object is zero.

Back

What is kinetic friction?

Front

Friction with motion between objects.

Back

when do you know you have moved from static to kinetic friction when looking at a graph?

Front

there is a linear slope and then a sharp drop followed by a flat line.

Back

Friction (Ff)

Front

the resistance that one surface or object encounters when moving over another.

Back

Applied Force (Fa)

Front

force applied from some other object (external force)

Back

What is Mass?

Front

measure of how much material (Scalar)

Back

Normal Force (Fn)

Front

Supporting force from a surface. Acts perpendicular to the surface.

Back

Tension (Ft)

Front

Force applied by a rope or string

Back

Which one needs more force, static or kinetic?

Front

static

Back

Net Force (Fnet)

Front

The sum of all forces acting on an object

Back

Is force a vector or scalar?

Front

vector with magnitude and direction

Back

What is force measured in?

Front

Newtons (N)

Back

Free Body Diagrams

Front

Back

When something is static,

Front

the applied force and gravity/friction is the same. (constant on a graph)

Back

Static Friction (Ffs)

Front

friction with no motion between objects.

Back

Inertia

Front

tendency to continue (resist to change)

Back

LESS MASS, -------- INERTIA

Front

LESS

Back

Gravity (Fg)

Front

Force applied from gravity AKA WEIGHT

Back

MORE MASS, ------- INERTIA

Front

Back

Formula for Gravity

Front

Fg= (mass)(gravity)

Back

What is the formula for static friction?

Front

Ffs = µS * Fn

Back

What is the formula for kinetic friction.

Front

Ffk = µK * Fn

Back

Force

Front

push or pull

Back

Newton's First Law (law of inertia)

Front

an object in motion/at rest will stay in motion/at rest unless acted upon by an external force

Back
