magnitude or direction of the force. In general‚ machines make the out put force or torque greater than input one. The magnitude of the force multiplication is called Mechanical Advantage. Here‚ two Mechanical Advantages and their differences will be discussed. One of them is Theoretical Mechanical Advantage and the other one is Actual Mechanical Advantage. Theoretical Mechanical Advantage‚ TMA‚ is defined as the ratio of the output force by the input (ideal) force. [pic] In contrast‚ Actual

hour and exert up to four times the force of gravity. Potential energy‚ kinetic energy‚ Newton’s laws of motion and the design of the batman rollercoaster functions. When you first start off you go up this big hill‚ you are increasing your potential energy‚ and when you reach the top you’re at maximum potential energy. At that moment when you start to rush down the other side of the hill you turn that potential energy into kinetic energy. Gravity is the force that pushes you down the hill. Then

product of the amount of force on an object and the time during which the force is applied F*∆t An impulse causes change in momentum ∆p (p=momentum) ∆p=m∆v F∆t=m∆v Main idea #2: In an isolated system‚ momentum before a collision is equal to momentum after the collision. When one object exerts a force on a second object‚ the second one exerts a force on the first that’s equal in strength and opposite in direction. When you have an isolated system with no external forces‚ the initial total momentum

describes how the mass of an object changes the way that it moves when acted upon (Jacplus 2013). This means that the more mass that an object has‚ the harder it will be to move. Mass can be calculated using the formula: F=ma * Where: F is the force (N) * m is the mass (kg) * a is the acceleration (m/s/s) If there are two balls and one has a mass of 1kg and the other has a mass of 2kg‚ then the ball that has a larger mass will be harder to push. This concept is used in modern day equipment

In formulaic terms. . The unit for thisd quantity is newtons per metre. Substituting the above equation (Hooke’s Law) into the equation‚ ‚ and therefore‚ . g here is the acceleration due to gravity‚ as the force on the spring consists of the weight of the bob.

……t2 = 4.081 √t2 = √4.081 ….t= 2.02 seconds to hit the ground. To determine the minimum speed required to clear 8m in 2.02 s just use D/T= 8/2.02= 3.96 m/s horizontally to clear 8 m from 20 m vertically. 5) Using acceleration = force * mass‚ we know the car had a force of 5000N‚ and a mass of 1500kg. 5000/1500 = -3.33 m/s deceleration. It took 5.6 seconds for the car to decelerate to 0‚ so multiply the deceleration/acceleration with the amount of time to obtain the initial speed of the vehicle

Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

Friction is the force resisting the relative motion of solid surfaces‚ fluid layers‚ and material elements sliding against each other. There are several types of friction: Dry friction resists relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces‚ and kinetic friction between moving surfaces. Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other.[1][2]
