For Lab 1‚ my partner and I will be demonstrating the law in which connects the period of the pendulum‚ expressed as T‚ to the length of the string‚ expressed a L. The system the lab will be based on will include a pendulum with a weight of W suspended at a fixed point by the string with a variable length of L and an angle theta to be measured using a protractor. The variable T will be measured as the period of time needed for the weight of the pendulum to swing back and forth once. For part 1 of

Newton’s First Law of Motion states explains that a force is needed to change the motion of an object. It states that objects do not move or change their speed unless a force acts upon them. The first law applies to gymnastics in some areas‚ particularly on the bars and the balance beam. For example‚ on the bars when a gymnast performs a giant she is doing complete revolutions around the high bar while keeping her body straight. In order to begin this skill she had to apply some force to get into

Projectile motion is a form of motion in which an object is thrown near the earth’s surface‚ causing it to move along a curved path under the action of gravity only. An example would be a football quarterback‚ when a quarterback throws the football in the air it goes upward and then travels back downward due to gravity. Gravity is the only force of significance that acts on the object which causes a downward acceleration. For example if Cam Newton throws a football over a long

Newton’s First Law Since an object at rest stays at rest‚ all roller coasters have to be pushed or pulled to get started. The roller coaster doesn’t move at first until it’s hard to the top on incline.Also because of inertia riders continue going at the same speed and direction unless another Force acts on them to change their speed or direction roller coaster cars will gain enough energy from the lift hill to be powered through the rest of the ride. Once put into motion‚ they will not stop until

A football player kicking a football is an example of a gross muscular skeletal muscle coordinating together to display the live-action potential of the chemistry between the functions of the nervous‚ muscular‚ and the skeletal system. For these actions to take place‚ the skeletal system must first be established and erected along with the cartilage‚ ligaments‚ and tendons attaching bones‚ muscle to bones‚ and articulation for movements. When a football player sprints on the field during a game

PART B 3. Power The explosiveness of sprinting is very crucial for every player in order to reach and possess the ball. Especially in offensive game that require a high amount of leg power to increase the speed output for the players. Balance Defensive players require a well balance in order to intercept the opponent forward by tackling the players or withstanding a good position. Without a sufficient balance for competing the opponent‚ it would potentially be able to lose the position from intercepting

REPORT Introduction I am doing a project that involves the ‘works’ of Gravity - discovered by Sir Isaac Newton. Gravity: the force that attracts a body toward the centre of the earth‚ or toward any other physical body having mass. For most purposes Newton’s laws of gravity apply‚ with minor modifications to take the general theory of relativity into account. My experiment is labeled The Marble Dropping experiment and has been done in many different ways using different methods and equipment.

The effects of surface type on the number of bounces Question How does the surface type affect the number of bounces of a tennis ball? Hypothesis If we drop the ball on a softer surface‚ then it will bounce less times than on a hard one. Materials List Floor Jacket Desk Binder (x2) Tennis ball Slow motion camera (phone) Metre stick Procedure Set up equipment (listed above). Drop the ball from a height of 1 metre on the first surface. Film the drop (in slow motion). Count and record the bounces

Background This experiment was used to test if a force with the same magnitude at opposite angles would equal to a net force of zero. If we equalize all the forces so we get a net gain force of 0 then no weight should touch the floor or the pulleys. We then tested if we added an extra weight with certain angle. We found out at what angle and what weight would equalize the force. The dependent variable is the force we used to equalize the force table. The controlled variables are the weight we initialized

Have you ever felt this horrible tension inside your chest and stomach? Did the circumstances you live in cause you to feel that way? This is what you call stress. An everyday tension of emotions that people from every culture‚ ethnicity‚ and race experience. People can understand and relate to the feeling of stress because it’s an emotion response that we were born with. Our ancestors used this emotion to their advantage. During this day and age‚ stress isn’t mostly taken as an advantage. It is
