  Describing Motion of an Object Directions: Read and write your answer on your answer sheet. Show your  solution on a  separate sheet. 1.     Teresa needs to walk a distance of 30 meters from her home to school. If she needs to be in school in 60 seconds,  how fast at least should she walk? 2.     If a bird flies a distance of 5 kilometers in 2 hours, what is its speed? 3.     If Pepito runs at a speed of 6 meters per second (6m/s), what distance does he travel in 10 seconds? 4.     Elena lives 200 m from her school. How long will it take her to reach her school if she walks at a rate of 2 m/s?  5. Miguel runs at a speed of 5 meters per second, what distance does he travel in          20    seconds?

  Distance is how far one thing from one thing.  It can be calculated by multiplying speed by time Formula:                  Distance   = speed    x   time       For example:   A bus travelling at an average rate of 50 kilometers per hour made the trip to town in 6 hours. How far does a bus trav el?     Distance = 50 kph   x   6 hrs = 300 km     Time can be calculated, by dividing the distance travelled   by an object to its speed.   Seconds (s), minutes (min)and  hours (hr) are examples the standard units of measurement for time . time===   Formula:                                   distance           ...

ACTIVITY A: Directions: Convert the following metric measurement to another unit. 1.)1 kilometer -                 __________ meter                                            2.) 1 decameter -              _________ centimeter                                   3.) 1 meter -                       _________ decimeter 4.) 1 centimeter -         ...

  What’s New Who is not in motion? It seems that everything is moving. From the time we wake up until we go to sleep, all our activities involve movement. We need to move in order to complete our tasks. Life without motion would surely be dull and boring. Motion will always be a part of our daily lives for it is motion that makes us fully alive as human. In science, distance should always be exact, measured accurately and based on a standard unit of measurement. Scientifically, distance should be measured by using measuring tools such as meter stick, tape measure, measuring wheel and ultrasonic distance measure. What Is It Motion may be defined as movement of an object brought about by force. When there is movement, there is motion. There can be no motion without force or set of forces. Forces, therefore, initiate and influence motion. Motion is relative. Consider the passengers in a moving car. The passengers inside the car do not consider themselves moving because they ...
