Use of force

Omar Alawad Math SL Mr. Sidat Stopping distance Introduction When driving on roads, drivers may see an obstacle ahead that requires them to apply brakes suddenly to stop. The distance covered by the car from the moment the driver applied brakes to the moment the car stops is called the stopping distance, which is also referred to as the braking distance. For a car travelling at an initial speed of , the stopping distance traveled by this car is given in the formula: The stopping…

I Anatomy of the shoulder The shoulder joint, as it is commonly called, is not a single joint but a complex arrangement of bones, ligaments and musculotendinous units that called the shoulder girdle. The primary role of the shoulder girdle is to provide a tremendous range of motion for positioning the upper extremity in space. The shoulder girdle also provides power and support for the upper extremity throughout and at the extremes of the range of motion. (19) The…

exerts this force between the floor and the player’s feet, causing an elevation of the player jumping and also the upward motion of the shooters body transfers energy into the player’s body,…

tapped against a wall. There are all kinds of forces to that, forces like contact force, Gravity, and normal force. Gravity exist among all objects in the universe. Like in the wall and the posters tapped against it. The two objects attract gravity towards each other. Connected to the example of the wall, and gravity, normal force is the supported force upon the two objects, because they are in contact with one another. Which also leads to contact forces, physics all comes back together as one…

and one of the main keys to have a good jump shot. To establish your form, you need to have your shooting hand behind the ball, and your other hand on the side of the ball. You want your shooting hand behind the ball because that is the hand you use to push the ball forward when you shoot. Your side hand is just to guide the ball and make sure you have control of the…

extends and rotates the arm to follow through and hit the ball. The triceps are then used and contract to get full power. The tennis player will then jump and the latissimus dorsi will come in use again. Then the racket will come down over the ball and hit it, the arm will now have done a full rotation. The serve uses a combination of horizontal and vertical movements. Horizontal abduction and external rotation occur during the backswing, with scapular retraction and depression into the loading…

Many children are forced to work now for the same reasons that they had to back during the Progressive Era. People have continuously tried to stop it with numerous movements, but the lack of money and amount of cruelty in certain people/families forces children to remain working. Child labor was really recognized in the 20th century. People made it so that children had to be at least 12 to work even for a small amount. This shows that people made an effort to stop child labor. Children have…

happy with their job, but there is still things that isn’t going to go their way which will ultimately lead to some complaint to a coworker or other. That’s the way life is, nothing is ever perfect, but for these detectives it seems that the task force is the perfect job. Even when Det. Halstead was scolded by Sergeant Voight about his actions, he didn’t complain or vent afterwards. I know that if I was scolded, even knowing my actions were wrong, I’d like to talk about it to someone. It seems…

In the system, focusing on the block, there are two forces residing on the block, which are its weight and its normal force that keeps the block from freefalling. However, normal force is perpendicular to the direction of the block’s displacement resulting on work done by the normal force because cos (90) is zero. Therefore, finding the total energy of the system, there is only initial potential energy due to the block’s…

In comparison to the group work done for paper one, I do believe this was an improvement, mostly because we wrote the paper as we worked through the problem. This not only helped with preventing the procrastination of typing the paper at the last minute, but gave us time to gain an understanding of what was going in the problem by going to office hours. What I feel needs improvement is my the communication between my partner and I. partner initiative to understand the problem. There were times…
