Chapter 3 Cornell Notes...

Description

Section 1 X

-Velocity and acceleration are not the same thing. An object moving with constant velocity has zero acceleration. When the velocity and the acceleration of an object are in the same direction, the object speeds up; when they are in opposite directions, the object slows down. -You can use a velocity-time graph to find the velocity and the acceleration of an object. The average acceleration of an object is the slope of its velocity-time graph.

Section 2

-If an object is moving with constant acceleration, its position-time graph is a parabola, and its velocity-time graph is a straight line. -The area under an object’s velocity-time graph is its displacement. -In motion with constant acceleration, position, velocity, acceleration, and time are related.

Section 3 X

-Free-fall acceleration on Earth is about 9.8 m/s^2 downward. The sign associated with free-fall acceleration in equations depends on the choice of the coordinate system. -When an object is in free fall, gravity is the only force acting on it. Equations for motion with constant acceleration can be used to solve problems involving objects in free fall.

Chapter # and Title: Chapter 3 – Accelerated motion

Core Concept: Acceleration is the rate of change in an object’s velocity.

Key Question: What is acceleration? Questions/ Vocab/Headings Notes/Charts/Graphs Acceleration:

The rate at which an object’s velocity is changing.

Velocity-time graph:

A graph on which velocity is plotted on the vertical axis and time is plotted on the horizontal axis.

Average Acceleration:

An objects change in velocity during some measurable time interval divided by that time interval.

Instantaneous acceleration:

The change in an object’s velocity at an instant of time.

Free fall:

The motion of an object when gravity is the only significant force acting on it.

Free fall acceleration:

The acceleration of an object due only to the effect of gravity.

Vector:

A quantity that has magnitude and direction.

Displacement:

A change in position having both magnitude and direction; it is equal to the final position minus the initial position.

Origin:

The point at which both variables in a coordinate system have the value zero.

Summary: -An object accelerates when its velocity changes – that is, when it speeds up, slows down, or changes direction. -For an object with constant acceleration, the relationships among position, velocity, acceleration, and time can be described by graphs and equations. -The acceleration of an object in free fall is due to gravity alone. Recall Questions: -How is acceleration different from velocity? -What information can you learn from velocity-time graphs? -What do a position-time graph and a velocity-time graph look like for motion with constant acceleration? -How can you determine the displacement of a moving object from its velocity-time graph? -What are the relationships among position, velocity, acceleration, and time? -How do objects in free fall move?...
