If two objects collide they each have the same momentum as they had before the collision?

The momentum of this case is equal to the summation of cross product of mass and velocity of both. How ever after the collision, some energy is converted into other form like sound and heat. This phenomena caused the momentum efficiency (e) In this case (masses are equal), e is equal to the ratio of the velovities summation of both masses between after and before hitting each other. e = ((V1'+V2')/(V1+V2));


Why pulling your arms in causes you to go faster?

When you are spinning there is a force called angular momentum that keeps you spinning and the angular momentum forms a ratio with the size of the object that is spinning so as you bring your arms inward, your size decreases increasing your angular momentum which spins you faster.


When an apple falls from a tree and strikes the ground without bouncing what happens to its momentum?

It is most likely because of the negligible amount applied on the world. Bear in mind the ratio of Earth's mass to the apple's mass. This ratio would be extremely large, thus we do not feel anything.

Which quantites remains unchanged if unsaturated air is lifted until it reaches the lifting condensation level?

When an unsaturated parcel of air is lifted, its potential temperature and the mixing ration are both conserved till it gets to the Lifting condensation level (LCL). Remember,the saturation mixing ratio decreases until it becomes mixing ratio at LCL.I gave the first answer and will like to say that the equivalent potential temperature is not conserved during this lifting.


Does linear motion have angular momentum?

I believe that any particle in linear motion must also have some angular momentum because all particles have spin. In the case of a photon the spin, wavelength and angular momentum all vary with the relative linear velocity. So in my point of view time itself is the ratio between relative linear and angular momentum.


What is the dilution ratio for momentum weed killer?

The dilution ratio for Momentum Weed Killer is typically 1 to 2 fluid ounces per gallon of water, according to the manufacturer's instructions. It is important to follow the label directions carefully to achieve effective results and avoid damage to plants or the environment.


How can one determine the coefficient of restitution in a physics experiment?

To determine the coefficient of restitution in a physics experiment, one can measure the initial and final velocities of an object before and after a collision. The coefficient of restitution is calculated by dividing the relative velocity of separation by the relative velocity of approach. This value represents the ratio of the final velocity of separation to the initial velocity of approach, providing insight into the elasticity of the collision.


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 can it be possible for two objects with different velocities to have the same momentum?

Two objects with different velocities can have the same momentum if one object has a greater mass and a lower velocity while the other object has a lower mass and a greater velocity. Because momentum is the product of mass and velocity, if the product of mass and velocity for each object is the same, their momenta will be equal.


What is the gyromagnetic ratio of silicone?

The gyromagnetic ratio of silicon is approximately 2.2126 x 10^10 rad T^-1 s^-1. It is a physical constant that describes the relationship between the magnetic moment and the angular momentum of a nucleus in a magnetic field.


How is Baseball used in golden ratio?

It is not. The Golden Ratio was known and used thousands of years before baseball was invented.


How can you make the momentum of a marble and a basketball equal?

-- Measure the weight of the marble. -- While on the same planet, measure the weight of the basketball. Since both measurements were made on the same planet, the ratio of the weights is the same as the ratio of the masses. -- Divide the big weight by the small weight (Wb/Wm); call the answer ' R '. -- Start the basketball moving, and measure its speed; call the speed ' S '. -- Make the marble move at a speed of ( R times S ). Their momenta are now equal. Momentum = (mass) times (speed), and that product is now the same for both objects.
