100

How do you calculate an unbalabnced force

You find the objects net force by adding or subtracting

100

What is the speed?

Distance: 10feet

Time: 10s

1 foot per second

200

What is the difference between speed and velocity

Velocity has a direction

200

How does an unbalanced force change the speed or direction of an object

More force is pushing one way ao it causes the object to accelerate in the direction of the unbalanced force

200

What is the speed?

Distance: 100m

Time:50s

2m/s

Acceleration

What is the difference between a balanced and unbalanced force

A balanced force will make the object not move for example when 2 people pull on opposite sides of a rope with euqal force

200N right

100N right

Newtons 3rd law

Every action has an equal but opposite reaction (ex: when you sit down in a chair you are applying force to the chair and the chair is applying force to you)
