State the 2nd Law of Motion
F = mass x acceleration
What is the unit of measurement of momentum?
Kg m/s
Push and pull on an object
Force
How do you use Newton's second law to find force?
F = m * a
Phil increased his speed from 2 m/s to 8 m/s in 3 seconds. What is his acceleration?
2 m/s
What is the 3rd Law of Motion
For every action, there is an opposite and equal reaction
What is the unit of measurement of Weight?
Newton
Speed with a direction
velocity
How do we get an object's acceleration from its velocity?
Acceleration = change in velocity/change in time
How much force is required for 2 kg object to have an acceleration of 2 m/s2
4 Newtons
What is Newton's 1st Law?
And object at rest remains at rest and an object in motion stays in motion unless it is acted upon by an unbalanced force
What is the unit of measurement of Force?
Newtons
Ability of an object to resist change in its motion
Inertia
How do we find the object's momentum?
Mass * velocity
What is the momentum of a 5 kg object with a velocity of 12 m/s?
60 kg m/s

Third Law
What is the unit of measurement of Impulse?
Newton second
Change in momentum of an object
Impulse
How do we find the Impulse?
Force * time
Which has a greater momentum: a 5 ton tank at rest or a 10 kg bicycle travelling at 30 m/s?
Bike!
What is the nickname of Newton's First Law
Law of Inertia
What is the unit of measurement of velocity?
m/s
Who formulated the 3 laws of motion? (full name)
Isaac Newton
What is the Law of conservation of momentum?
m1v1i + m2v2i = m1v1f+ m2v2f
