PPT-Chapter 3 3.1 What is acceleration?

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.

Before landing, the ball went through several changes in motion. It sped up in the pitcher’s hand, and lost speed as it traveled toward the batter. The ball stopped when it hit the bat, changed direction, sped up again, and eventually slowed down. Most examples of motion involve similar changes. In fact, rarely does any object’s motion stay the same for very long.. What Is Motion?. Motion. is when an object changes place or position. To properly describe motion, you need to use the following:. Start and end position?. Movement relative to what?. How far did it go?. Physics. Turning:. Turning counts as a form of acceleration because the direction of the velocity vector changes.. Turning requires a force that is perpendicular to the current motion of an object..

What is acceleration?. If you’re traveling in a car at a constant speed of 50 mph, are you accelerating?. No, you’re not. . Acceleration is the rate of change of velocity. . Acceleration. In order for acceleration to occur, velocity MUST be . 3.2. 3.2 Acceleration. Think about a car at a stop light. When the light turns green, the car starts moving and the car’s velocity increased. The car began accelerating. Acceleration is the change in velocity divided by the time it took the change to occur.
