SCIENCE Do you know that... Objects move at different rates which can be measured by speed and velocity. Speed is the rate of distance travelled by a moving object definition of speed can be written as: per unit of time. This speed = (dis * tan c * e * t * r * a * v * e * l * l * e * d)/(timeoftravel) In the mathematical formula above, you can calculate the speed of a moving object by simply dividing the distance the object travels by the time it takes to travel that distance. Let us look at how the sample problem below is solved using the formula. Solution: Step 1: Write the formula. Step 2: Substitute given numbers and units. Step 3: Solve for the unknown variable. Sample Problem: A car travels 400 kilometers in 7 hours. What is the speed of the car? peed = (dis * tan c * e * t * r * a * v * e * l * l * e * c)/(timeoftravel) d = (400kilomet * epsilon)/(7hours) speed speed= 57.14 kilometers/hour or 57.14 km/hr The most common instrument installed in vehicles like motorcycles, cars. trucks, and airplane which can measure their speed is the speedometer. Speed is expressed in different units such as: meter per second (m/s) kilometer per hour (km/hr) mile per hour (mi/hr) Velocity, on the other hand, refers to the speed of a moving object a given direction. Directions can be described by using the terms North, South. West or East. The units for velocity are the same as those of speed. It is simpler to understand that velocity is just speed plus direction. with You are a great reader! Now that another you learned activity. Go ahead and answer Activity B about speed and velocity, it is time to work on Activity B Directions: Examine the figure below and answer the following questions. Situation: A ball is made to move across a 10 seconds. start second 2 seconds 10-meter distance from point A 10 meters 4 seconds seconds to F for and 8 seconds Questions: 1) How far did the ball go at 2 seconds? 2) At point C. what is the distance of the ball from it starting position? 3) What is the distance travelled by the ball at point E after 8 seconds? 4) What is 5) What the average speed of the ball from point A to F? is the velocity of the ball?​
