Who Cares Anyway

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

While some children were playing “house” others were taking part in constructive play. In this stage, toddlers have a deep understanding of what various objects can do and will now try to build things with the toys and everyday objects they find around them. One child had a box of blocks and was building a train track. Once he finished he assembled a line of trains to ride along the track he had just built. He repeatedly made noises that trains usually make such as “choo-choo.” Other children were interlocking Lego blocks and creating various structures while some were playing with play-dough and sculpting

1. The ball has potential energy while momentarily at rest at the top of the path.

The purpose of this experiment was to create a model that showed the motion of a spinning body and to test the accuracy of said model. The model was created by calculating the measurements of the orbital period of a stopping mass for six varying mass ratios and then comparing them to the model equation derived from the equation for centripetal force. The primary results of the lab were in agreement with the predicted values, therefore our degree of confidence in our data was high.

The objective of this lab was to explore the behavior of centripetal acceleration and identify the relationships between the acceleration and several forces acting on the object.

Circular motion is one of the fundamental building blocks for understanding the physical world because it is so common. This interactive lets you examine the basic ideas of kinematics and forces for objects moving in circular motion.

Doodle, the handicapped boy, is mentally developed slower and is challenged to learn how to walk with the help of his brother, six years older than he is. Doodle's brother didn't want to take Doodle everywhere in a go-kart, so the both of them were determined to make Doodle walk by his birthday, and he does.

There are 3 Laws of Motion developed by Isaac Newton in 1687, in his book “Mathematics Principles of National Philosophy”(Hall,Nancy).Newtons first law of motion says that an object will stay at rest until a external force is applied. Also know as inertia(Hall, Nancy). Gravity affects it buy pulling the counter weight down which pulls the the opposite side which has the sling and projectile up launching the projectile(Saimre tanol). For gravity to be most effective the counter weight must be at least five times heavier than projectile(Saimre tanol). Centripetal force is a big factor in calculating trebuchet factors. the definition of centripetal force is a force that acts inwards on any object that rotates or moves along a curved path and is directed toward a center point(Centripetal force). In this case centripetal force is good. when the projectile is released centripetal force pulls it inwards which makes it go farther and be more accurate with out centripetal force the projectile would go straight up or straight down(Centripetal

For example, you may review a book from Grades 1, 4, and 7 to meet the requirements of this assignment. If your sample textbook does not contain any of the graphs listed below, please indicate that as you complete the table.

9) Since you are plotting displacement on the y-axis and time on the x-axis, this is an example

Everyday Brother pushed Doodle to the limit, training to be just like him. Overwhelmed with pride Brother felt unstoppable while little Doodle continued to struggle and abide to Brother’s commands. Through the cruelty Doodle endured Hurst symbolically portrayed that pride can be a dangerous thing. Unable to complete the list a frustrated Brother decides to double their efforts by making Doodle row against the strong currents. Breathless within minutes, they row to shore. Walking back lightning struck across the sky and water droplets dissipated from the clouds. Brother angry and ashamed of having an incapacitated sibling he quickly walked through the rain. Doodle already weak and tired could not keep up. Brother walked faster. Faster and faster until Doodle lagged far behind, but Brother didn’t care. All he cared about was how embarrassing it was to have brother who couldn’t do anything a normal boy could do. Without him even noticing Doodle had tripped. “Brother don’t leave me, please !” he cried. Brother continued to walk… until he heard a crack that made his ears

The ± signs correspond to the acceleration of gravity and the sign is chosen according to the direction of motion; if the motion is upward the value (-g) is taken and if it is down, the value (+g) is taken.

Any external influence on a body causes an equal and opposite reaction from the body

In the first stage of the experiment, children were brought to the experimental room by the controller and the model, who was in the hallway outside the room and was invited to come in and join in the game. The room was set up for playing and the activities were selected because they had high interest for nursery school children. One area was arranged was a child’s play area, where there was a table and chair, potato prints and stickers. After settling the child in its corner the adult model was brought to the other side of the room where there was a small table, chair, tinker-toy set, a mallet and a big inflatable Bobo doll. After the model was seated the experimenter left the experimental room (Diessner, 2008).

For describing the motion of rigid bodies, we shall introduce the key concept of ‘centre of mass’. This concept enables us to understand how we can apply justifiably the Newton’s laws of motion, in essentially the same form to objects of large size including even the astronomical objects like the planets and the stars.
