Inertia
What is Inertia?
Inertia is the state that if an object is moving forward, it will stay moving in a straight line until another object disturbs it and if a object is stationary, it will stay stationary unless another object moves it.
What is momentum?
Momentum is mass and velocity.
What is Newton's 1st law?
An object will not change its motion unless a force acts on it.
What is gravity?
The force that pulls everything on Earth down.
Does Inertia connect with Newton's laws?
Yes.
What do the letters in the formula for momentum stand for?
P = Momentum
M = Mass
V = Velocity
What is Newton's second law?
An object's acceleration is dependent upon the amount of force that is applied to it, and its mass.
Who discovered gravity?
Isaac Newton
If Inertia connects with Newton's laws, what law is it?
The third law.
How do rockets use momentum?
The exhaust gases go in one direction, so while the rocket is going in a different direction, it has to balance itself and find momentum.
What is Newton's third law?
Every action has an equal and opposite reaction.
How much gravity is on Earth? (A guess is fine)
9.807 m/s2
What connection does Inertia have with Newton's laws?
It follows Newton's third law.
What is momentum's formula?
P=mv
What profession/s/ did Newton do?
Physicist and Mathematician
How much gravity is on the moon? (A guess is fine)
1.62 m/s2
