Momentum is a property of matter which causes matter to maintain velocity (speed and direction) unless acted on by unbalanced forced. This applies anywhere, from in space, in the air, on the ground, under ground, or under water.
Once a swimmer is moving he/she has momentum. Momentum is a vector quantity is calculated by multiplying mass by velocity. When moving through a fluid, whether it be air or water, a body encounters resistance. This resistance causes momentum to be lost to the fluid around the body, and the body slows down. Normally a constant force such as a waving a fin, or spinning a propellor is needed to counter the loss of momentum. Aero/hydrodynamic shapes will lower resistance allowing the body to retain momentum for much longer, and reduce demand for a compensating source of power.
What else can I help you with?
Can momentum apply a force?
No, momentum is a property of an object in motion that is determined by its mass and velocity. It does not apply a force itself, but can be used to analyze how forces acting on an object change its motion.
How does the conservation of momentum symmetry apply in the context of physical interactions between objects?
The conservation of momentum symmetry states that in a closed system, the total momentum before a physical interaction between objects is equal to the total momentum after the interaction. This means that the combined momentum of all objects involved remains constant, showing that momentum is conserved in the interaction.
How does the conservation of momentum apply to a closed system?
The conservation of momentum states that in a closed system, the total momentum remains constant before and after any interaction between objects. This means that the total momentum of all objects in the system does not change unless acted upon by an external force.
What is the approach to solving a 2-dimensional momentum problem?
To solve a 2-dimensional momentum problem, you need to break down the problem into its horizontal and vertical components. Use the principle of conservation of momentum to analyze the initial and final momentum in each direction. Apply the equations for momentum in each direction and solve for the unknown variables.
How does the concept of conservation of momentum apply to the motion of the spheres in a Newton's Cradle?
The concept of conservation of momentum applies to Newton's Cradle by demonstrating that the total momentum of the spheres before and after a collision remains constant. When one sphere strikes the others, it transfers its momentum to the next sphere, causing a chain reaction that conserves the total momentum of the system.
What would you do to impart the greatest momentum to an object?
To impart the greatest momentum to an object, you would need to apply the greatest force over the longest time interval. This can be achieved by increasing both the force and the duration of contact between the object and the force. This would result in a greater change in the object's momentum.
How to apply the law of conservation of momentum to study explosive force?
To apply the law of conservation of momentum to study explosive force, you would need to consider the initial momentum of the explosive device (before detonation) and the final momentum of all fragments and debris (after detonation). By analyzing these quantities, you can understand how the explosive force is generated and how it propels objects outward based on the principles of momentum conservation.
1 In a collision that is inelastic the total what after the collision is not the same as before the collision?
Hi, in line with Newton's laws of motion the momentum before and after a collision is always conserved (when no external force is applied to change the systems momentum). In elastic collisions we can apply the conservation of momentum and conservation of energy principles. In inelastic collisions we can only apply the conservation of momentum principle. Energy is not conserved in inelastic collisions because energy is lost through small deformations, noise, friction, etc. We can compute the coefficient of restitution that helps determine this degree of energy loss from impulse-momentum equations.
How does the law of conservation apply to a game of pool?
There are several laws of conservation; please clarify which one you mean. For example, there is the law of conservation of mass, of energy, of momentum, of rotational momentum, of electrical charge, and others.
How does the conservation of momentum apply in an inelastic collision?
In an inelastic collision, the total momentum of the system is conserved, meaning that the total momentum before the collision is equal to the total momentum after the collision. However, in an inelastic collision, some of the kinetic energy is transformed into other forms of energy, such as heat or sound, so the objects involved stick together after the collision.
What are some common 2D momentum problems and what are the solutions to these problems?
Common 2D momentum problems involve objects colliding or moving in different directions. To solve these problems, you can use the principles of conservation of momentum and apply vector addition to find the final velocities of the objects. It is important to consider the direction and magnitude of the momentum vectors to accurately solve these problems.
How does the principle of conservation of energy and momentum apply to the dynamics of a closed system?
The principle of conservation of energy and momentum states that in a closed system, the total amount of energy and momentum remains constant. This means that energy and momentum can change forms within the system, but the total amount will always stay the same. This principle is important in understanding how energy and momentum are transferred and distributed within a closed system during dynamic interactions.
