Recall: Acceleration is the rate at which velocity increases or decreases If an object is accelerating is not experiencing uniform motion
Formulas: To solve acceleration questions use: Can use if acceleration is uniform
Note: Your textbook goes through sample problems on pg 220/221 in a step- by-step method.
A car acquires a velocity of 32m/s by accelerating at 4.0m/s 2 for 5s. What was its initial velocity? v 2 = 32m/s a = 4m/s 2 t = 5s v 1 = ?
v 1 = 30m/s t = 3s v 2 = 0m/s d = ? The brakes are applied on a car traveling at 30m/s. The car stops is 3s. What is the car’s displacement & average acceleration? a = ?
How long does it take an airplane accelerating from rest at 5.0m/s 2 to travel a distance of 360m? a = 5m/s 2 v 1 = 0m/s d = 360m t = ?
A ball rolls at an initial velocity of 4m/s up a hill. Five seconds later it is rolling down the hill at 6.0m/s. What is the acceleration? v 1 = 4m/s t = 5s v 2 =–6m/s a = ?
A person biking at a velocity of 10m/s speeds up for a distance of 24m, accelerating at a rate of 3m/s 2. What is the bike’s final velocity? v 1 = 10m/s d = 24m a = 3m/s 2 v 2 = ?
How long does it take a car traveling at 22m/s accelerating at 4.0m/s 2 to travel a distance of 20m? v 1 = 22m/s a = 4m/s 2 d = 20m t = ?
Kinematics- Acceleration Chapter 5 (pg ) A Mathematical Model of Motion.
Aim: How do we use the kinematics formulas? Do Now: What is the difference between average velocity and instantaneous velocity? Quiz Tomorrow.
Kinematics Day 3. Kinematic Equations Used in situations with uniform acceleration.
Equations of Motion Review of the 5 Equations of Motion.
Motion Review Physics TCHS.
Acceleration. The rate of change in velocity Acceleration The rate of change in velocity Examples…. –Speeding up Positive acceleration –Slowing down.
Motion An object is in motion if ___________ from another object ______________.
Need for (More) Speed. Of course not every object is going to travel the same VELOCITY all the time.
All quantities in Physics can be categorized as either a scalar or a vector quantity. A scalar quantity has magnitude (amount) only without direction.
Motion. What Do We Mean By Speed? Exactly how fast are you running? How many meters do you run for each second? Do you always run the same number of meters.
Acceleration When an object is changing its velocity, we say that the object has acceleration Acceleration is how fast velocity is changing To accelerate,
Aim: How can we calculate average velocity when distance is unknown? Do Now: What is the average velocity between A and B? Velocity (m/s) Time (s)
Kinematics AP Physics 1. Defining the important variables Kinematics is a way of describing the motion of objects without describing the causes. You can.
1. What distance will a train stop in if its initial velocity is 23 m/s and its acceleration is m/s/s? 1058 m xvivfatxvivfat.
2.2 Acceleration Physics A.
Section 2 Acceleration. Students will learned about Describing acceleration Apply kinematic equations to calculate distance, time, or velocity under.
COACH O’ROURKE. Introduction Remember: velocity is __________________________ Acceleration is the rate of change in velocity So think back: which of the.
