Strictly speaking weight is the force of gravity acting on an object. It should not be confused with the objects mass.
Weight ⇔ force
When something is on the moon it weights less but its mass is the same.
Something special about gravity is that in the absence of air friction, all objects accelerate down at the same rate irrespective of their weight because as a objects weight increases, so does its mass.
Take the equation..
F = ma
or
(weight of an object) = (its mass) x (its acceleration)
When an objects weight doubles so does it mass, so the acceleration does not change.
What else can I help you with?
Does an object with momentum always have energy?
Not if it's potential energy. Only objects with kinetic energy have momentum.
The weight of an object is an example of?
The weight of an object is an example of the physical properties of the object and the effect of gravity on a mass.
Does the mass of the car effect the speed?
A cars weight affects its speed by varying its momentum. If the car has more weight, it has more momentum. With more momentum comes more inertia.(definition: inertia- an objects resistance to change in direction or movement) If the car has a lot of weight, it will speed up slower and stop slower because the cars inertia and momentum keep propelling it forward. If a car has less weight, it will speed up faster and stop faster because the momentum of the car is less than that of the heavier car. A: It is called the power to weight ratio.
How would throwing an object affect the fingerprint left on it?
Assuming the fingers are in contact to push or pull the object, the amount of pressure put on the fingers to move an object would increase with the weight of the object. This results because friction force that must be overcome to push or pull the object is proportional to the object's weight. [Elementary physics.] And the print definition varies with the pressure used to implant the fingerprint. If the fingers are not pressed hard enough against the object, some of the print will be missing from the object. If they are pressed too hard, the print will be smudged and ill-defined. And that's the answer. Fingerprints are likely to be smudged with moving heavy objects, missing in part with moving light objects, and better defined when moving medium weight objects. All this assumes we're using the fingers in all cases. In fact, we'd probably use the palms of our hands if we are moving heavy objects; so the fingers might not even touch the object.
What is friction affected by?
Weight and surface affect friction. The more mass an object has more friction that will occur ex:/ It would be harder to slide an elephant across a floor than a hockey puck. This is because the large amount of friction on the elephant would slow it down. The smoother the surface the less friction. ex:/ There will be more friction on a floor of sandpaper than there would be on a floor of ice.
What is the force that a moving object has which is dependent on the speed and weight of the object is?
The force you are referring to is called momentum. Momentum is the product of an object's mass and its velocity, so it depends on both the speed (velocity) and weight (mass) of the object.
Which is not a force weight air friction resistance momentum?
Momentum is not a force. Momentum is a property of a moving object that depends on its mass and velocity. Forces, such as weight, air resistance, and resistance, act upon objects to change their momentum.
Which of the quantitative properties would double if you doubled the mass of an object?
-- weight -- momentum when moving -- kinetic energy when moving -- force on it needed to produce a given acceleration -- potential energy at a given height
What is difference between static weight and dynamic weight?
Static weight is the total amount of weight a table can safely hold in a static position. The dynamic weight is the weight placed in an object and then put into motion. The difference therefore is the weight being stationary or in motion
Does an object with momentum always have energy?
Not if it's potential energy. Only objects with kinetic energy have momentum.
Why is more force needed to change the motion of a heavy and fast moving object compared to a light weight and slow moving obect?
More force is needed to change the motion of a heavy and fast-moving object because of its momentum, which is the product of its mass and velocity. The momentum of an object indicates the amount of force required to change its motion, so heavier objects with higher velocities require more force to change their direction or speed compared to lighter objects moving at slower speeds.
What is the term for weight multiplied by velocity?
The term for weight multiplied by velocity is "momentum." In physics, momentum is defined as the product of an object's mass (weight) and its velocity, typically represented by the equation ( p = mv ), where ( p ) is momentum, ( m ) is mass, and ( v ) is velocity.
Why is velocity needed to measure momentum?
In physics, the momentum of an object is the amount of energy it has moving in a direction. It is a product of its mass (weight) and its velocity (speed and direction) as in (momentum = Mass times velocity). Momentum changes when speed is increased or decreased, its direction changes, or its mass changes. An example of changing momentum is an object in space such as a meteor falling to the earth. Gravity can make it come down faster increasing its momentum. Atmospheric friction heats up the object causing some of it to burn away reducing its mass and decreasing its momentum. Another example of momentum is a snowball rolling down a snow covered mountain. Gravity pulling it down increases it speed (velocity) and momentum. Rolling down in snow, it accumulates snow, gets larger, increasing in weight (mass) and momentum.
What are the two factors which determine the momentum of a body?
Momentum depends on the mass and the velocity of an object. In physics, P=mv, momentum equals mass times velocity.
Speed times weight equals?
The product of speed and weight gives momentum, which is a measure of an object's motion. This relationship is described by the equation momentum = mass x velocity.
What is the effect of acceleration on an object which is not moving?
An object which is not moving is not experiencing any acceleration, other than the acceleration due to gravity, which, along with mass gives it its weight. The upward force (normal force) acting on the object is equal to but opposite to its weight, and all of the forces acting on the objects are in equilibrium so the net force is zero Newtons.
An elephant and a mouse would both have zero weight in gravity-free space If they were moving toward you with the same speed would they bump into you with the same effect Explain?
Weight is mass*gravity, in zero gravity objects have zero weight. But they still have mass! When one object bumps another they under go a collision. Which can be explained by transfer of energy or conservation of momentum. In the case of energy, KE=1/2mv2 the mouse and the elephant have different masses so therefore different kinetic energy. Or in terms of momentum (mass*velocity), again the mouse and elephant have different masses and therefore different momentums at the time of impact. Therefore the reaction you feel will be different.
