## Is momentum equal to energy?

Some people think momentum and kinetic energy are the same.

They are both related to an object's velocity (or speed) and mass, but momentum is a vector quantity that describes the amount of mass in motion. Kinetic energy is a measure of an object's energy from motion, and is a scalar.

## Is momentum equal to the mass?

In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity.

## Is momentum equal to p?

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.

## Is momentum equal to the product of mass and speed?

momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton's second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.

## How do you convert momentum to force?

They are related by the fact that force is the rate at which momentum changes with respect to time (F = dp/dt). Note that if p = mv and m is constant, then F = dp/dt = m*dv/dt = ma.

## What is momentum in physics class 9?

Momentum is how we measure mass that is in motion. Any moving object will have momentum. Under the law of physics, the object's momentum equals mass times velocity. Momentum = Mass x Velocity.

## What is momentum in class 11?

Hint : Momentum is a measure of the velocity of a moving object. Higher the velocity, the higher the momentum. Higher the mass of the object, the higher the momentum. It can also be related to force by Newton's second law of motion.

## What is momentum short answer Class 9?

Hint: Momentum can be defined as the function of an object's mass and velocity. Momentum can be well defined as the measure of the kinetic energy of the object. In simple words, the momentum is the product of mass and velocity. Complete answer: In simple words, the momentum deals with the quantity of the motion.

## What is momentum by Brainly?

Explanation: Momentum is a quantity with a value and a direction. It is the product of the mass of an object and its velocity. Momentum is conserved in elastic collisions. The unit of momentum is a kg·m/s, which is also equivalent to a J·s (a Joule·second).

## What is momentum Class 9 Brainly?

Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity. it formula = mass × velocity. so it's SI unit is = kg×m/s = kg m/s.

## Which of the following equations below defines momentum?

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).

## What is impulse illustrate the effect of impulse?

Explanation: Impulse is a term that quantifies the overall effect of a force acting over time. It is conventionally given the symbol J, end text and expressed in Newton-seconds. J=f delta t.

## What is Newton's 3rd law sometimes called?

Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.

## Is impulse equal to momentum?

The impulse experienced by an object is the force•time. The momentum change of an object is the mass•velocity change. The impulse equals the momentum change.

## Is tension a force?

A tension force in physics is a force developed in a rope, string, or cable when stretched under an applied force. Tension is acted along the length of the rope/cable in a direction that is opposite to the force applied on it. Tension can also at times be referred to as stress, tensity or tautness.

## Is static friction?

Static friction is a force that keeps an object at rest. Static friction definition can be written as: The friction experienced when individuals try to move a stationary object on a surface, without actually triggering any relative motion between the body and the surface which it is on.

## Is air resistance a force?

The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object.

## What is electricity force?

The attractive or repulsive interaction between any two charged objects is an electric force. Like any force, its effect upon objects is described by Newton's laws of motion.

## What is amber effect?

Amber is petrified tree resin, and the ancients knew that when you rub an amber rod with a piece of cloth, the amber attracts small pieces of leaves or dust. This amber effect, namely when rubbed with a cloth, the ability to attract some other objects is due to static electricity.

## Is gravity a contact force?

Gravitational force is an example of a non-contact force.

## What is the frequency of the AC voltage line?

50 Hertz

Typically, either 110-volt AC (110V) or 220-volt AC (220V) is used. Most countries use 50Hz (50 Hertz or 50 cycles per second) as their AC frequency.
