Transcript: Speed You find the speed by distance divide by time it is distance divide by time because the distance shows the lenght of the person or thing and shows whitch unit you need. The time is how far you go in that distance. Then you take distance divide by time. Like if you went 20 feet in 10 seconds your speed would be 2ft per second. Speed:the rate at which something moves, happens, or functions The objective is to find the speed of a person walking 9 feet. Matrials: Tape, yard stick, timer Procedure 1. Set the tape for 9 feet 2. Have a person walk 9 feet and time the person 3.Take the 9 feet and divide it by the persons time to figure out their speed. To find speed it is distance divide by time.
Transcript: "Speed" Our Object Our object has a motion transmission system because, when the front wheels rotate the rear wheels rotate too. Also when the stick moves by the force of the rubber band the stick rotates which causes the wheels to rotate too. The most close systems to our object are: •Friction Gear Systems When you want to move the car, you have to rotate the stick the opposite direction you want it to go. •Belt and Pulley When the rubber band is rotated to move, the force of the rubber band makes the car move. Yes, it could have because, the wheels that we used are heavy, so we could have used lighter wheels so the car can move faster and farther. The type of deformation our object has is: •Elastic •Plastic •Elastic is for the rubber bands that we used for the motor of the car. •Plastic is for the plastic basket we used for the body of the car. Pupose of Object Guiding Control Our object can go up a hill(z-axis) and go forward(x-axis). Do you think your object could have been designed better? Made by Jora Khalsa and Martin Taylor (cc) photo by Metro Centric on Flickr Thank you Amanda for this website!! There are only two links for our object which is: •Flexible The wheels on the car are made of plastic, which means the wheels can bend. •Removable Basically everything is removable on our object. Properties of materials Also if we could have used stronger sticks. When the rubber band is attached to the stick, the stick begins to bend, which will lead to a result of beaking by the force soon. Constraints •The constraints of our car is: •Torsion •Torsion, the two ends of the kebab stick. If you twist the sticks too much the rubber band attached to it will snap. The properties of materials the car has is: •Hardness •Hardness, the wheels on the car cannot be dented because they are made of thick plastic. Bonus... Type of Deformation Description of links Thank you for listening! Adhesion & Friction (cc) photo by Metro Centric on Flickr Degrees of Freedom Our object moves rotationally. If you want the car to move , you have to move the stick in the direction you want to go in a rotationally way, when the wheels spin, they move rotationally. Motion Transmission systems and Motion Transmitions Types of Movement (cc) photo by jimmyharris on Flickr The rubber on the wheels is meant to provide adhesion. The purpose of our object is basically to move forward or backwards. The car has rotational control, because the stick in between, moves in a rotatinally . (cc) photo by Franco Folini on Flickr
