What is the momentum of the 25 kg object traveling at a speed of 4 miles per second?
What is the momentum of the 25 kg object traveling at a speed of 4 miles per second?
Expert-Verified Answer As asked in question the momentum of the 25kg object moving at 4 m/s is 100 kilogram meters per second (kg·m/s).
Does mass increase momentum?
Here are some simple rules for momentum.. Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.
Does an object have to be moving to have momentum?
It is the product of an object’s mass and velocity. An object at rest has a momentum of 0. This helps distinguish momentum from inertia. An object must be in MOTION to have momentum.
What variables are required to determine an object’s kinetic energy?
Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed.
What is the momentum of a 4 kg ball?
A 4 kg ball has a momentum of 12 kg m/s.
What is the formula for momentum and speed?
Momentum, Impulse, and the Impulse-Momentum Theorem p = m v . p = m v . You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v). Therefore, the greater an object’s mass or the greater its velocity, the greater its momentum.
Why is P used for momentum?
This meaning is also related to the word ‘impetus’ which is the earlier term used for ‘momentum’. The word ‘impetus’ gives the meaning as to go and rush upon which was explained by the term Petere. Hence, momentum is represented by the letter P.
What is the SI unit of momentum?
| Momentum | |
|---|---|
| SI unit | kilogram meter per second (kg⋅m/s) |
| Common symbols | p, p |
| Other units | slug⋅ft/s |
| Dimension | MLT−1 |
How to find momentum?
Step 1: List the mass and velocity of the object. Step 2: Convert any values into SI units (kg, m, s). Step 3: Multiply the mass and velocity of the object together to get the momentum of the object.
When momentum is zero?
An object can have zero momentum when either its mass or its velocity is zero. Since negative mass doesn’t exist, the velocity should be zero and thus, the object must be at rest.
Is Impulse a vector?
Impulse is a vector, so a negative impulse means the net force is in the negative direction. Likewise, a positive impulse means the net force is in the positive direction.
What is the M in physics?
Mass (symbolized m) is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System (SI) is the kilogram (kg).
What is the momentum of a body of mass 25 g?
A body of mass 25 g has a momentum of 0.40 kg m/s.
What is the formula for momentum in KG?
In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s. Newton’s second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.
How is the momentum of an object calculated?
Momentum (P) is equal to mass (M) times velocity (v).
How much does the momentum of a body of mass 5 kg change when its speed?
Hence when A body of mass 5 k g undergoes a change in speed from 20 m s – 1 to. 20 m s – 1 . The momentum of the body decreases by 99 k g m s – 1 .
