Describing Motion
Ch. 6 Lesson 1
Ch. 6 Lesson 1
The starting point you choose to describe the location or position of an object
What is reference point?
An object at rest is represented by a ________ line on a speed-time graph
What is flat/horizontal?
a push or pull on an object
What is force?
The tendency of an object to resist a change in motion
What is inertia?
Describes an object's distance and direction from a reference point
What is position?
A graph that shows how the speed of an the object changes during each interval of time
What is a speed-time graph?
A noncontact attractive force that exists between all objects that have mass
What is gravity?
This law states that the acceleration of an object is equal to the amount of force acting on the object divided by the object's mass
What is Newton's Second Law of Motion?
The difference between the initial position and the final position
What is displacement?
Constant speed is represented by a __________ line on a distance-time graph
What is straight?
A contact force that resists the sliding motion between two objects that are touching
What is friction?
Two objects that exert force on each other
What is a force pair?
The speed and the direction of a moving object
What is velocity?
A graph that shows how distance and time are related
What is a distance-time graph?
Forces are ________________ when the net force acting on an object does not equal 0
What is unbalanced?
This law states that if the net force acting on an object is zero, the motion of the object does not change
What is Newton's First Law of Motion?
A measure of how quickly the velocity of an object changes
What is acceleration?
This is always measured on the x-axis of a motion graph
What is time?
A force that pushes or pulls an object without touching it
What is noncontact force?
This law states that when an object exerts force on a second object, the second object exerts the same amount of force in the opposite direction
What is Newton's Third Law of Motion?
