Force
What is Force?
A push or a pull that one object exerts on another.
Speed = Distance / Time
What is the unit for force?
Newtons
What is friction?
A force that opposes the motion of one object sliding over another
Who is Issac Newton?
A man that discovered gravity
What is Net Force?
The combined effect of all the forces acting on an object.
The action or process of moving or being moved
Seconds, Minutes, Hours
What is Gravity?
A force that attracts objects
What did Issac Newton create in order to figure out gravity?
Issac Newton created Calculus in order to figure out gravity
How do you calculate force?
Force = Mass x Acceleration
What is Velocity?
Speed in a given direction
What is the unit for distance?
Meters, Kilometers, Miles
How do you calculate weight?
Weight = Mass of an object x gravitational pull
What is Newton's First Law?
An object at rest stays at rest and an object in motion stays in motion unless acted upon by another force.
What is an unbalanced force?
Forces that cause a change in the motion of an object.
What is constant speed?
Speed that never changes
What is the unit for speed?
M/S, MPH, etc
What is Mass?
Mass is how much matter is in an object (solid, liquid, and/or gas).
What is Newton's Second Law?
Forces make objects move, change direction, and speed up.
Balanced forces acting on an object...
...Never change the object's motion
How can the speed of an object be changed?
The speed of an object can be changed by speeding up, slowing down, or changing direction
What is the unit for mass?
Kilograms, Grams, etc
If friction was gone for just one second, would it be good or bad?
Bad
What is Newton's Third Law?
For every action there is an equal and opposite reaction.
