Phys1111 - Representations of Motion

tells us how fast an object is moving and in what direction. But what if the velocity is changing? This is what acceleration describes-how quickly the velocity of an object is changing In this activity we will learn about Names मभ पीस Acceleration Activity Period 6 Date Section 1 Introduction, To answer the question How do things move? we can provide the velocity of a Oojecwhat when an object is accelerating and how to calculate the rate of acceleration. Examples of Acceleration: The following motions describe objects that are NOT accelerating A bird flies at a constant speed of 10 m/s in a constant direction of North A train travels at a constant velocity of 45 mi/hr South A car travels along a straight section of highway at a constant 100 km/hr The following motion describes objects that ARE accelerating A bird, flying at a speed of 5 m/s, speeds up to 10 m/s in a constant direction of North A person runs at a constant speed of 3 mi/h while turning from the North to the East A car…
