How do you find the speed of an object
Distance divided by time
How do you calculate an unbalabnced force
You find the objects net force by adding or subtracting
What is the speed?
Distance: 10feet
Time: 10s
1 foot per second
What is the difference between speed and velocity
Velocity has a direction
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
What is the speed?
Distance: 100m
Time:50s
2m/s
An object speeding up or slowing down
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
What is the net force?
50N right
30N left
20N right
Newtons 1st law
An object in motion stays in motion and ann object at rest stays at rest
Newtons 2nd law
F=ma
What is the net force?
100N left
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)
What is the net force?
500 N Left
600 N right
100 N right
