Inertia
What is Inertia?
The idea that an object will continue its current motion until some force causes its speed or direction to change.
Newton's first law of motion is also known as what?
The law of inertia.
What is friction
The resistance that one surface of object encounter when moving over another
How many laws of motion did Issac Newton discover?
What is force?
A push or pull
Why does a faster car take longer to slow down than a slow car?
Because the car requires more force to stop when its going faster.
Newton's first law states that an object in motion stays in what?
What 2 factors make an object in motion come to a rest.
Friction and air resistance.
What did Isaac Newton explain?
He explained why things move.
Why do we have seatbelts?
So you don't go flying through a windshield.
What causes inertia to stop?
Friction
Newton's first law states that an object at rest stays at what?
Rest
If a rolling object has no friction or air resistance what will happen to the rolling?
It will keep rolling until an external force stops the object.
Whats another thing Isaac Newton discovered?
He discovered Calculus.
Everything on the surface of the earth would get flung.
What affects inertia the most?
The mass of the object.
Who created Newton's first law.
Issac Newton
An object in motion goes in a straight line unless acted upon what?
External forces.
When did Isaac Newton die?
Age 84
What force is acting on every object that is on the ground or on something?
Gravity
Does an object gain or lose inertia.
No
What is the nickname of the first law of motion
The law of laziness.
The resistance of an object to change its motion, is the definition for what word.
Momentum.
On what month and day was Isaac Newton born?
December 25
What is the difference between motion and inertia?
Motion is when an object is moving and inertia is an objects resistance to change.
