all of the roller coasters without ever giving any thought to the physics behind the ride. There are several components of physics which contribute to the thrill of roller coasters, including gravitational forces, the law of conservation of energy, friction, centripetal force, and normal force, just to name a few. Gravity, the law of conservation of energy, and friction all play major roles in the functionality of roller coasters. A roller coaster ride typically begins with an ascent, powered…

Problem: Is there a relationship between the mass of an object and the force of static friction and force of kinetic friction of that object? If so, what type of relationship is there? Background: Friction is a type of force that is created when two surfaces move across one another. Static friction is friction between two or more solid objects that are not moving relative to one another. Kinetic friction is the amount of friction between two objects that are moving relative to each other.…

Drag force is an aerodynamic force which acts parallel and opposite to the motion of the object when it moves through a fluid. It is caused by friction and differences in air pressure. There are many factors can affect the magnitude of drag force as with aircraft lift. The drag depends linearly on the shape and size of the object moving through the air. The object’s cross-sectional shape determines the form drag which is created by the pressure variation around the object and affects the…

be used to explain how and why stuff move. These laws that Newton came up with are still used today. Newton’s first law of motion states that “an object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force acts on it”. An example of the first law of motion is if you are driving in your car at a very high speed and hit something, like a brick wall or a tree, the car will come to an instant stop, but you will keep moving forward. This is why cars…

on coefficient of friction [e.g., [55], [62]]. Frictional sliding force F is proportional to the force N normal to the interface at which sliding is taking place. This model can be expressed by: However, the above equation fails to give accurate prediction in high normal stress conditions. Several studies applied modified Coulomb friction law [e.g., [42], [40], [63],[41]] in which critical friction stress depends on pressure normal to the tool-chip interface, coefficient of friction, and…

are no forces acting on it? Explain. a. No, forces would still be acting on an object if its acceleration is zero. Acceleration is only the change in velocity and in the F=ma equation, the F stands for net force. For example, if a car was traveling at a constant velocity, it would still have forces such as gravity, friction, and normal force acting on it. 2. Only one force acts on an object. Can the object have zero acceleration? Can it have zero velocity? Explain. a. If only one force acts on…

balance these forces. the only forces exerted upon the riders are the force of gravity and the normal force The force of gravity is at all times directed downwards and the normal force is at all times directed perpendicular to the seat of the car. Since the orientation of the car on the track is continuously changing, the normal force is continuously changing its direction. Feelings of weightlessness and heaviness are associated with the normal force; they have little to do with the force of…

is when external forces acting on a particle are balanced (zero resultant), the particle will be in equilibrium. But when external forces acting on a particle are not balanced, the particle will move in the direction of the resultant with magnitude ma. We use Newton’s second law to calculate the acceleration of a particle. Once the acceleration of a particle is known, we can apply equations of kinematics to obtain the…

of this experiment is to verify Newton’s 2nd Law of Motion. Introduction Newton’s 2nd Law states that when an external net force acts on an object, the acceleration of the object is proportional to the net force, and it also occurs in the same direction. The acceleration is also inversely proportional to the net force. Thus, the net force, which is the sum of all the forces acting on an object, is equal to the mass of the object multiplied by its acceleration. In this experiment, a cart with a…

Let n ̂ denote the unit normal drawn to the interface of two media 1 and 2 and [ ] denote the jump in the enclosed quantity in crossing interface from 1 to 2. The boundary conditions on the velocity vector for inviscid fluid flow are simple because here, the normal component of the velocity alone need to be continuous where as for viscous fluid flow both the normal and tangential components of the velocity must be continuous and hence the boundary…
