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.

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.
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.
Why is it important that momentum id a vector?
It is important that momentum is a vector because it has both magnitude and direction. This enables us to analyze how an object's motion changes in response to external forces. By treating momentum as a vector, we can apply principles of vector addition and subtraction to better understand the overall motion of an object.
How do you calculate the new velocity so that momentum remains same?
apply conservation of momentum theory- m1v1=m2v2 where m1 is the initial mass, m2 is the final mass, v1 is the initial velocity and v2 is the final velocity.
How can someone decrease the momentum of an object?
To decrease the momentum of an object, one can apply an external force in the direction opposite to the object's motion. This force should act over a period of time to reduce the object's velocity, ultimately lowering its momentum. Alternatively, the object can also collide with another object of equal or greater mass in the opposite direction, transferring momentum through the collision.
How do you decrease momentum over a short period of time?
To decrease momentum over a short period of time, you can apply an external force in the direction opposite to the momentum. This force can be applied through friction, air resistance, or another external mechanism to slow down the object or change its direction quickly. Alternatively, you can transfer momentum to another object in the opposite direction through a collision or interaction.
If an object is moving at a constant velocity and you want to change it's momentum you would change it's?
The answer is velocity.
How does momentum apply to basketball?
In basketball, momentum refers to a team's or player's speed and power in a game. It can be positive or negative, influencing the flow and outcome of the game. Teams can build momentum through scoring runs, defensive stops, or individual plays that ignite the team and the crowd.
What is the applications of angular momentum?
Angular momentum is used in various applications in physics and engineering, such as in analyzing the motion of objects in rotation (like spinning tops or satellites), understanding the behavior of gyroscopes, and explaining phenomena like the conservation of angular momentum in celestial bodies. It is also crucial in quantum mechanics for describing the rotational properties of particles.
