Newton's Laws
1st law
What area of science did Newton study?
Physics
How much mass does an object have if it is acceleration to 5m/s2 with a Force of 500? (units)
100kg
What is the unit used for force?
Newtons (N)
increases with increasing mass.
inertia
The most important thing about the 3rd law is that forces occur...
in pairs
Newton's 3rd law of motion states:
Every action has an equal and opposite reaction.
Calculate the force of a 20,000kg spaceship reentering the Earth's atmosphere.
200,000N or 200 kN
What is the unit used for mass?
kilogram (kg)
The greater the mass the slower the...
acceleration
Newton's 2nd law equation involving acceleration is...
a= F/m

What is the unit used for acceleration?
m/s2
A smaller cannon ball leaves a cannon much faster than a heaver one.
2nd law
Which law would best be used to describe friction acting on a moving object?
1st law
What is Netown's equation for solving time. (hint: remember velocity).
t = mv/F
What is the mass of an object that needs a force of 7000N to increase its speed from rest to 100m/s in 3 seconds? (units)
210kg
What is the force of gravity on earth? (with units)
10 or 9.8m/ss
When you are on the subway train and the train suddenly stops but your body continues to move forward.
1st law
This is the law we would use to understand how mass directly affects force.
2nd law
The force that is responsible for attracting or pulling objects towards each other.
Gravity
How much time did it take for a 10,000kg plane to land traveling at 60m/s with a force of 500N? (double points if answer is in minutes).
1200 seconds or 20 mins.
1N equals
1 apple
