How did Isaac Newton discover gravity?
When was Isaac Newton born?
January 4th, 1643
What did Isaac Newton major in?
Mathematics and Physics.
When you stand on the floor, the force of your body pushing down on the floor is...
balanced by the force of the floor pushing up on your body.
If the following objects are all moving at the same velocity, which of the objects have the greatest momentum?
The object with the largest mass.
Who made the 3 Laws of Motion?
Isaac Newton
When did Isaac Newton die?
March 31st, 1727
What is velocity?
The speed of something in a given direction combined with the direction of the object.
Who was Isaac Newton?
Isaac Newton was a great scientist who changed physics and mathematics in the 1700s.
Name every vocabulary word for this week.
Newton's First Law of Motion
Newton's Second Law of Motion
Newton's Third Law of Motion
Inertia
Acceleration
What is gravity?
The force that attracts a body toward the center of the earth, or toward any other physical body having mass.
What is friction?
The resistance that one surface or object encounters when moving over another.
What represents the 1st Law of Motion in everyday life?
Inertia
What represents the 2nd Law of Motion in everyday life?
Kicking a Ball. When we kick a ball, we exert force in a specific direction which is the direction in which it will travel.
What represents the 3rd Law of Motion in everyday life?
When you jump, your legs apply a force to the ground, and the ground applies an equal and opposite reaction force that propels you into the air.
What would happen if there was no friction, and you threw a ball?
It would keep going on forever, but because it exists that wouldn't happen.
Why don't we fall off the earth?
What is the 1st Law of Motion's second name?
The Law of Inertia
What is the 2nd Law of Motion's second name?
It doesn't have a name but it can be described as ''force equals mass times acceleration''.
What is the 3rd Law of Motion's second name?
The Action Reaction Law
What is an acceleration?
A change in speed or direction.
What is Inertia?
Resistance to a change in motion.
What is Newton's First Law of Motion?
An object at rest tends to stay at rest. An object in motion tends to stay in motion, with the same direction and speed.
What is Newton's Second Law of Motion?
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed. (To accelerate the object.)
What is Newton's Third Law of Motion?
For every action (force) there is an equal and opposite reaction (force). Forces are found in pairs.
