What is a force and how does it affect

the motion of an object?

Today we will…

-Identify the conditions under which an

object will continue with same motion

or change motion

• Go over key concepts quiz #2 from last week

• If you don’t understand a question, make sure

to ask (you may see these questions again)

Forces

Net force

Unbalanced force

Balanced force

Look for the secret apple. As

soon as you see it, stand up and

say “Newton”

“Newton”

A force is a push

or a pull

Forces are measured in Newtons

(N)

Examples: Contact, gravity,

friction

Like velocity and acceleration,

forces are described not only by

how strong they are, but also by the

direction in which they act

Force is a vector

Net Force

•The overall force on an

object after all of the

forces have been added

together

A

C

B

The net force is pushing to the right

The net force is pushing to the left

The net force is 0

Forces

Unbalanced Forces

•An unbalanced force can

cause an object to start

moving, stop moving, or

change direction (which is

acceleration)

Unbalanced Forces

•An unbalanced force

acting on an object will

change the object’s

motion

Unbalanced Forces

•When there is a net

force acting on an

object, the force is said

to be unbalanced.

Balanced Forces Balanced Forces

•Equal forces acting on an

object in opposite

directions

Balanced Forces

•Balanced forces acting on

an object will not change

the object’s motion

Balanced Forces

•When you add equal forces

exerted in opposite

directions, the net force is

zero
