Vocabulary
The state in which one object's distance from another object is changing.
What is motion?
The combination of all the forces acting on an object.
What is net force?
Newton's 1st Law of Motion is also called the Law of ...
What is Inertia?
This type of friction occurs when an object rolls across a surface.
What is rolling friction?
Formula for speed
What is speed equals distance/time?
What is a reference point?
The force applied when one object actually touches another object.
What is a contact force?
Every action force is paired with an equal an opposite reaction force.
What is Newton's 3rd Law of Motion?
This type of friction causes object to slow down and stop.
What is sliding friction?
Formula for force
What is force equals mass x acceleration?
The tendency of an object to resist a change in motion.
What is inertia?
An example of a noncontact force
What is gravity?
An object's mass directly affects how much force is needed to accelerate the object.
What is Newton's 2nd Law of Motion?
A force that acts in a direction opposite to the direction of the object's motion.
What is friction?
The speed at which an object travels IN A GIVEN DIRECTION
What is velocity?
The push or pull exerted on an object.
What is a force?
When two forces are equal in strength but opposite in direction.
What is a balanced force?
The greater the object's mass, the greater the inertia.
What is Newton's 1st Law of Motion?
Fluid friction is often referred to as "what" when describing how an object moves through the air.
What is air resistance?
The value of the acceleration due to gravity
What is 9.8m/s^2?
The distance an object travels per unit of time.
What is speed?
The unit for the strength of the force.
What is a Newton?
For every action there is an equal (in strength) but opposite (in direction) reaction.
What is Newton's 3rd Law of Motion?
This type of friction acts on objects when they are resting on a surface.
What is static friction?
Formula for average speed
What is the average speed equals the total distance traveled/total time?
