What else can I help you with?
Is the momentum of an object moving in a circular path constant?
No, the momentum of an object moving in a circular path is not constant. The direction of the velocity of the object changes constantly, leading to changes in its momentum.
Does an object moving at a constant speed have momentum?
Yes, an object moving at a constant speed does have momentum. Momentum is the product of an object's mass and velocity, so as long as the speed is constant, the momentum of the object will also remain constant.
As a moving object's velocity decreases its momentum decreases?
False. The momentum of an object is the product of its mass and velocity, so if the velocity decreases while the mass remains constant, the momentum of the object will decrease.
Why does velocity stay constant with decreasing momentum?
As far as we can tell, it doesn't. Momentum is defined as (mass) times (velocity). There appear to be only two ways in which momentum can decrease: either the mass has to magically evaporate, or else the velocity has to decrease. Since mass conservation is a nearly fundamental law of nature, that leaves us with velocity as the only way to change the momentum of a moving body.
If the velocity is constant does that mean that there is no impulse?
Not necessarily. Impulse Fdt=change in momentum which could be written as mdv (constant mass, velocity changing) or dmv (changing mass, constant velocity - the so-called conveyor belt problem. Imagine a hopper filled with (say) coal is feeding the coal on to a conveyor belt. The mass of the belt increases with time, so a force has to be applied to it to keep it moving at constant velocity.
What property that a moving object has due to its mass and velocity?
The property that a moving object has due to its mass and velocity is momentum. Momentum is calculated as the product of mass and velocity, and it represents how difficult it is to stop a moving object.
Determine if the momentum of an object moving in a circular path at constant speed is constant?
Yes, it can. Initially, an object will be accelerating downward (with an acceleration equal to g - f, where f is the force of air resistance). During this period, mass is constant but velocity is continually increasing, so momentum increases as well. However, because f is dependent on v (the speed of the object relative to the air), at a certain velocity, the force of air resistance will equal gravity, and the object will stop accelerating (this velocity is known as "terminal" velocity). At this point, the object will fall with constant speed, and momentum will remain constant.
As a moving object's velocity decreases its momentum decreases. Please select the best answer from the choices provided T F?
False. Momentum is the product of an object's mass and velocity, so if the velocity decreases, the momentum will decrease only if the mass remains constant. If the mass changes, then the momentum will change accordingly.
As a moving object's velocity decreases does its momentum decreases?
Yes, if a moving object's velocity decreases, its momentum will also decrease as momentum is directly proportional to velocity. Momentum is calculated as mass multiplied by velocity, so any change in velocity will result in a change in momentum in the same direction.
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.
Does a body moving with uniform acceleration have momentum?
Yes, a body moving with uniform acceleration has momentum. Momentum is the product of an object's mass and its velocity, and acceleration is the rate of change of velocity. As long as the object is moving and has mass, it will have momentum.
Is the momentum of an object moving in a circular path at a constant speed is constant?
determine if the momentum of an object moving in a circular path at constant speed is constant.
