Newton's Laws
Equal and opposite reaction
What is Newton's Third Law of Motion?
An object's change in position relative to the reference point
What is motion?
A thrown object is called this
What is a projectile?
Increasing speed, decreasing speed, or changing direction
What are ways to accelerate?
Resistance created by one object sliding over another.
What is Sliding Friction?
An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an unbalanced force.
What is Newton's First Law of Motion.
The distance traveled by an object divided by the time interval during which the motion occurred
What is Speed?
A force that pulls objects toward each other.
What is Gravity?
When an object slows down
What is deceleration?
The resistance that one surface or object encounters when moving over another
What is friction?
The study of the laws of motion
What is mechanics?
The speed of something in a certain direction
What is velocity?
When gravity is the only force acting on an object.
What is free fall?
The rate at which velocity changes
What is acceleration?
The force when a solid object moves through a fluid.
What is fluid friction?
When one object exerts a force on a second object, the second object exerts a force back on the first object.
What is Newton's Third Law of Motion?
It causes an object to move
What is an unbalanced force?
The measure of gravitational pull on an object, dependent on the object's mass.
What is Weight?
A diver begins accelerating as soon as they do this.
What is leap from the platform?
This force acts upon objects that are not moving.
What is static friction?
The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object
What is Newton's Second Law of Motion?
There is no change in an object's motion
What happens when balanced forces act in opposite directions on an object?
An acorn and a leaf fall from a tree at the same time but the leaf lands after the acorn because of this.
What is air resistance?
The rate of change of velocity per unit of time
What is Acceleration?
These surfaces provide the least amount of friction.
What are smooth surfaces?
