## Acceleration

Acceleration. Section 2.2. Standards Covered. PS – 5.3 Explain how changes in velocity and time affect the acceleration of an object PS – 5.4 Use the formula a = (v f -v i )/t to determine the acceleration of an object. Acceleration. Acceleration – rate of change of velocity

## Acceleration

Acceleration. Acceleration is another way to measure and describe the motion of an object. Acceleration : (a) rate of change of velocity over time. An object is considered to be accelerating when it speeds up , slows down , or changes direction .

## Speed/Motion Notes!

Speed/Motion Notes!. Motion – an object is in motion if it changes position to a reference point r=d/t Constant speed g speed does not change Average speed g speed changing (total distance/total time) Instantaneous speed g the speed of an object at any given instant.

## Memory II Reconstructive Memory Forgetting

Memory II Reconstructive Memory Forgetting. Observe this crime scene. Memory Biases. Memory is better for meaningful significant features than for details of language or perception  gist is remembered better than detail. What does a penny look like?. Reconstructive nature of memory.

## Acceleration

Acceleration. What does it mean to accelerate anyway??. TO ACCELERATE YOU MUST CHANGE YOUR VELOCITY!! VELOCITY CHANGES IF…. 1. Increase Speed 2. Decrease Speed 3. Change Direction

## Learning and performance curves

Learning and performance curves. Progress score. McGill-theorist said that most learning research shows 4 general learning curves, these display how the learning is progressing e.g. Blocks of trials. . Linear -where equal amounts of progress occur with each performance.

## Chapter 3: Newton’s Second Law of Motion

Chapter 3: Newton’s Second Law of Motion. Force and Acceleration. Galileo Developed the Concept of Acceleration. Galileo used inclined planes (ramps) He found that balls rolling down inclines rolled faster and faster Acceleration = change in velocity/ time interval.

The basketball constantly changes velocity as it rises and falls. Describing changes in velocity, and how fast they occur, is a part of describing motion. What Is Acceleration?. How are changes in velocity described? The rate at which velocity changes is called acceleration.

## Motion

Motion. Speed, Velocity, and Acceleration. Frames of Reference. The object or point from which movement is determined Movement is relative to an object that appears stationary Earth is the most common frame of reference. Questions. What is the frame of reference for the sunset?

## MOTION

MOTION. Chapter 11. How do you know something is moving?. Depends on your frame of reference. A frame of reference is the location from which motion is observed. Most common: the earth. Measuring distance. Distance: the length of a path between two points.

## What is speed?

What is speed?. Speed is a measure of how far an object moves in a given time. . This car is travelling at 60 mph. This means the car travels 60 miles every hour. This jet is travelling at 350 m/s. This means the jet travels 350 metres every second. How is velocity different to speed?.
