Raghul M.S 3 years, 1 month ago

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. ... See also conservation law; angular momentum.

ANSWER

A ball is thrown up with a velocity of 20m/s^-1 what is the time taken of the flight, neglecting the air resistance

Posted by Raj Shree 3 years, 1 month ago

CBSE > Class 09 > Science

1 answers

Sia ? 3 years, 1 month ago

Given:-

Velocity of the ball through which it is thrown

Acceleration due to gravity (g)

To find:-

The time of the flight, neglecting the air resistance.

Solution:-

When the body comes back to the initial position, the displacement s = 0

We know that,

s = ut – 1/2gt

s = ut – 1/2gt 0 = ut – 1/2gt ut = 1/2gt

t = 2u/g. Here ‘t’ is the time of flight, i.e.,

Therefore, Time of flight, t =

Thus, time of flight neglecting the air resistance=4s

Explain mass

Posted by Rishipal Singh 3 years, 1 month ago

CBSE > Class 09 > Science

3 answers

Ganesh P 3 years, 1 month ago

Mass is the fundamental attribute of any physical body. All the objects have a matter inside them and the measurement of the matter is the mass. The total mass of the system is assumed to be constant. This means that the mass remains unaffected by the gravitational field strength, regardless of the location, the object or person is in. Mass has a magnitude that is usually measured in kilogram and gram. Therefore, it is a scalar quantity. We are on earth and we measure things on earth with earth's gravity. If your weight is 70 kg which means you weigh 70 kg and the scale would read it 70kg or 154 lbs. Mass Definition Mass is defined as the measure of the matter inside a body. In physics, mass is a quantitative measurement of inertia. Let’s understand the concept of mass by understanding Newton's second law. For example, a body of mass, ‘m’ is moving with an acceleration ‘a.’ The force, ‘F’ is applied to the body given by, F = m . a Here, mass is a measure of its resistance to acceleration when a force is applied on to the body. Therefore, greater the mass of a body, the minimum change produced by an applied force. Mass Meaning Mass is referred to as the amount of matter contained in a body. For example, a human body has bones, muscles, tissues, RBC, WBC. As combined, they form a body’s mass. A person or object may be weightless on the moon because of lack of gravity while he maintains the same mass at all places without considering his location.
