PPT-Acceleration and Free fall

2016 Measuring Distance Meter international unit for measuring distance 50 m 1 mm Calculating Speed Speed S distance traveled d the amount of time it took t S dt. Galileo increased the inclination of inclined planes.. Steeper inclines gave greater accelerations. . When the incline was vertical, acceleration was max, same as that of the falling object.. When air resistance was negligible, all objects fell with the same unchanging acceleration.. 3. Acceleration and Free Fall. Acceleration. The changing of an object’s velocity over time.. Average Acceleration. SI Unit: m/s. 2. Vector Quantity.  . Acceleration. When velocity and acceleration are in the same direction, the speed of the object increases with time.. Vector calculations. Free Fall. Defined:. Any object who’s acceleration is caused by gravity. Therefore:. Acceleration . = . 9.8 m/s. 2. Velocity will . depend on how far an object has traveled. Velocity is constantly increasing. http://. www.aplusphysics.com. /courses/honors/kinematics/. honors_kinematics.html. Unit #2 Kinematics. Objectives and Learning Targets. Use kinematic equations to solve problems for objects moving at a constant acceleration in a straight line and in free fall.. Kinematics. is the branch of physics that describes the motion of points, bodies (objects) and systems of bodies (groups of objects) without consideration of the causes of motion.. Kinematics. One-dimensional kinematics involves movement along one axis.. One-Dimensional Motion. Mr. Richter. First Quarter Categories. Displacement. Upward Launches. Free Fall. Negative Acceleration. Displacement. A man walks 15 m to his left and then 10 m back to his right. What is his displacement?. A. ccelerated . M. otion. 3.1 Acceleration. Acceleration. Acceleration – the rate at which an object’s . ____________________________. EX: 9.8 m/s/s = 9.8 m/s. 2. Acceleration . Acceleration. Vector - . Unit 2B: Motion – Part 6. Free Fall. Objects whose only acceleration is due to gravity are in . free fall. .. Theoretically, objects in free fall continue to accelerate as long as they are falling.. or . Gravity is making me do it!!. What is . free fall?. Free Fall is the motion of the body when . air resistance is negligible. . and the action can be considered . due to gravity alone. .. Free fall Video. Chapter 3 Section 4. Usually omit instantaneous. Interpretation: The rate of change at which . f. is changing at the point x. Interpretation: Instantaneous rate are limits of average rates.. Example. Galileo defined acceleration as the rate of change of velocity.. Formula!. a. = . Δ. v / t. Things that affect acceleration: . Speeding up. Slowing down. Changing direction. Time. Free Fall. When air resistance does not affect the motion of an object, then the object is in free fall.. Place on your desk:. *Calculator. *. Orange. homework chart . *. Merrily We Roll Along Lab. 1) What force on earth causes falling objects fall downward?. 2) True or False: The less steep the incline, the smaller the acceleration.. Imagine there is no air resistance and that gravity is the only thing affecting a falling object. . An object moving under the influence of the gravitational force only is said to be in . free fall. . the heavier object will fall faster than the lighter one. the lighter object will fall faster than the heavier one. both objects will fall at about the same rate. How does a fall object behave?. Aristotle’s said (A) is correct. .
