## Chapter 1: Motion Section 1: Describing in addition to Measuring Motion How do you recogniz

Baertlein, Lisa, Food Industry Reporter has reference to this Academic Journal, PHwiki organized this Journal Chapter 1: Motion Section 1: Describing in addition to Measuring Motion How do you recognize motion An object is in motion when its distance from another object is changing Movement depends on your point of view What is a reference point A place or object used as long as comparison to determine if something is in motion An object is in motion if it changes position relative to a reference point What is the basic unit of length The meter a little longer than a yard

What do scientists use to measure the length of an object smaller than a yard A centimeter one hundredth of a meter, so there are 100 centimeters in a meter A millimeter There are 1,000 millimeters in a meter How do scientists measure long distances The kilometer There are 1,000 meters in a kilometer How do scientists calculate speed Speed the distance the object travels in one unit of time Rate tells you the amount of something that occurs or changes in one unit of time Speed = distance time

What is constant speed If the speed of an object does not change, the object is traveling at a constant speed What is average speed Most objects do not move at constant speeds as long as very long To find average speed divide the total distance by the total time Car trip What is Velocity Speed in a given direction When you know the speed in addition to direction of an objects motion, you know the velocity of the object Example 15 km/hour westward

How do you graph motion You can show the motion of an object on a line graph in which you plot distance against time Time is along the x-axis in addition to distance on the y-axis How do you interpret motion graphs A straight line indicates a constant speed The steepness depends on how quickly or slowly the object is moving The faster the motion the steeper the slope Section 2: Slow motion on Planet Earth According to their explanation, known as the theory of plate tectonics, Earths plates move ever so slowly in various directions

How fast do plates move Some small plates can move as much as several centimeters per year, whereas other move only a few millimeters per year How can you calculate the distance an object has moved Rearrange the speed as long as mula Distance = Speed x Time Converting units choose a conversion factor that will allow you to cancel units Section 3: Acceleration What is Acceleration The rate at which velocity changes In science, acceleration refers to: increasing speed decreasing speed changing direction

How do you calculate acceleration To determine the acceleration rate of an object, you must calculate the change in velocity during each unit of time Acceleration = Final velocity Initial velocity Time How do you interpret graphs to determine acceleration The acceleration at any moment is equal to the slope of the velocity time graph at that moment in time Acceleration vs. Constant speed
