Rollercoasters have different types of forces involved. Two of the main forces experienced are called potential energy and kinetic energy. Potential energy is the energy an object has depending on the position of it. For example the higher an object is the higher the potential energy is and the lower an object is the less potential energy it will have. Kinetic energy is also a main type of force that is involved with rollercoasters. Kinetic energy is the energy an object will have as it is in motion

Air resistance is an opposing force often known as drag force. Air resistance acts in the opposite direction to snow skier’s velocity and can either harm or enhance performance of the athlete. The flow of air around an object causes the unavoidable effect of drag and is influenced by the size‚ shape‚ surface‚ and overall speed of an object (John Polson‚ 2013). Air resistance is present in snow skiers and can inhibit their performance in a race greatly if the proper precautions and positions are

elements of the skin age‚ how the skin reacts to harm or injury‚ and why scars form unique shapes. ("Anatomy & Physiology of Adult Friction Ridge Skin") Understanding how friction edge skin responds when it contacts a surface can give assistance‚ when examining the friction ridge impressions. This essay will introduce the properties of skin and its relationship to friction-skin impressions as well as other characteristics of skin‚ such as: scarring of skin‚ condition of the skin‚ distortion and elasticity

An air track is an apparatus that simulates the effects of frictionless motion. A known mass is attached to an air-cart on an air-track apparatus. Attached by string‚ the air-cart is pulled by the known mass when hung over a pulley. A spark timer will mark the motion at a frequency of 10 Hz (10 dots/s) on a strip of paper called ticker tape. The air-track will supply air through the apparatus to simulate a frictionless environment‚ enabling the system of masses to move without an applied force or

Collisions may involve many different qualities but momentum is a main aspect of a collision. There are three main types of collisions: elastic collisions‚ inelastic collisions‚ and completely inelastic collisions. All collisions involve momentum because momentum is conserved in all collisions. Momentum is also known as mass in motion and a vector. Momentum equals mass times velocity‚ which is found during a collision. Momentum is an important part during a collision because it determines the outcome

Argument: Acceleration is caused by two factors‚ mass and force. The graph above shows the relationship between acceleration and force as proportional. As the force upon the car in the experiment increased‚ the acceleration of the car increased by a similar proportional. This complies with Isaac Newton’s second law of motion‚ the law of acceleration‚ which describes acceleration and force as two proportional measures in the equation F (force) = m(mass) x Ac(acceleration)‚ also described in
