This means that a 1,000-kg car moving north at 20 m/s has a different […] In physics, we define momentum mathematically as the multiplication of mass and velocity as seen in this equation: p = m * v. Momentum is the product of mass and the velocity of the object. Note that a body's momentum is always in the same direction as its velocity vector. To fully describe the momentum of a 5-kg bowling ball moving westward at 2 m/s, you must include information about both the magnitude and the direction of the bowling ball. Note the definition says velocity, not speed, so momentum is a vector quantity. If an object has a higher mass and is moving with higher velocity, its momentum will also be higher. p = m v m/s. (CBSE 2010, 2011) Answer: Momentum of a body is defined as the product of the mass and velocity qf the body. 9th class physics notes on chapter Force Laws of Motion sub topic-INERTIA, If follows from first law of motion that is absence of any eternal force, a body continues to be in its state of rest or of uniform motion along a straight line Momentum is the most important quantity when it comes to handling collisions in physics. Momentum as a Vector Quantity. (CBSE 2015) Answer: Momentum is a vector quantity. Momentum definition is - a property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity; broadly : a property of a moving body that determines the length of time required to bring it to rest when under the action of a constant force or moment. Linear Momentum - definition Linear momentum is a vector quantity defined as the product of an object's mass, m, and its velocity, v. Linear momentum is denoted by the letter p and is called momentum for short. Is momentum a scalar or a vector quantity ? are solved by group of students and teacher of Class 9, which is also the largest student community of Class 9. Momentum The quantity of motion possessed by a moving body is known as momentum of the body. Note that a body's momentum is always in the same direction as its velocity vector. The only difference in angular momentum is that it … The unit of momentum are kg. SI Unit of Momentum. Define momentum of a body. Linear Momentum - definition Linear momentum is a vector quantity defined as the product of an object's mass, m, and its velocity, v. Linear momentum is denoted by the letter p and is called momentum for short. Momentum of an object of mass m moving with a velocity v is the product of it. Momentum is a vector quantity.As discussed in an earlier unit, a vector quantity is a quantity that is fully described by both magnitude and direction. From the definition of momentum, it can be concluded that the mass and velocity of the object are of equal importance for calculating momentum. m/s. Filed Under: Class 9, Force and law of motion Tagged With: conservation of momentum, total momentum About Mrs Shilpi Nagpal Author of this website, Mrs Shilpi Nagpal is MSc (Hons, Chemistry) and BSc (Hons, Chemistry) from Delhi University, B.Ed (I. P. University) and has many years of experience in teaching. The unit of momentum are kg. The Questions and Answers of How will you define conservation of momentum? As from Newton’s llnd law, rate of change of momentum … It is denoted by p p = mv Its SI unit is kg-ms-1. If the answer is not available please wait for a while and a community member will probably answer this soon. Let us consider a truck and … As mentioned above, the units of momentum will be the product of the units of mass and velocity. Question 28. Mass is measured in kg and velocity in ms-1, therefore, the SI unit of momentum will be kgm/s(-1).. Other Momentum Units Momentum is a physical quantity defined as the product of mass multiplied by velocity. So the other important aspect of momentum is mass.
