What did Aristotle say about impetus?
If Aristotle were correct, then it would be possible to move an arrow or rock by simply agitating the air behind them. This, however, was contrary to experience. He concluded that violent motion occurs by the mover transferring to the object of motion an incorporeal kinetic power—later known as impetus.
What is meant by momentum with example?
Answer: Momentum is defined as the quantity of motion of the body. All objects have mass therefore if an object is moving, then it has momentum – it has its mass in motion. We can change momentum by changing its mass or changing its velocity, a mass unit is multiplied by a velocity unit to provide a momentum unit.
Who introduced impetus?
John Philoponus
The theory of impetus was an auxiliary or secondary theory of Aristotelian dynamics, put forth initially to explain projectile motion against gravity. It was introduced by John Philoponus in the 6th century, and elaborated by Nur ad-Din al-Bitruji at the end of the 12th century.
What is Galileo law of motion?
Galileo’s claim that force causes acceleration is inseparable from his claim that bodies do not require a cause to continue their movement. This latter claim states that a body in motion will continue its motion so long as no factor disturbs that motion. This principle is called the principle of inertia.
How do you use momentum in a sentence?
Momentum sentence example
- Using her momentum , he swung her over his head.
- Her body continued its momentum down the hill and she fell, twisting so that she wouldn’t fall on the kid.
How does momentum work in physics?
Momentum can be defined as “mass in motion.” All objects have mass; so if an object is moving, then it has momentum – it has its mass in motion. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
What is the difference between momentum?
That is why; an object does not move in case of the balanced force applied, and hence the velocity remains zero. It implies that momentum will also be zero as momentum = mass * velocity….Difference Between Force and Momentum.
| Force | Momentum |
|---|---|
| Force = mass * acceleration or f=ma | Momentum = mass * velocity or p=mv |
What is the difference between impulse and 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.
What is momentum short answer?
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.
What is momentum one word?
noun, plural mo·men·ta [moh-men-tuh], mo·men·tums. force or speed of movement; impetus, as of a physical object or course of events: The car gained momentum going downhill.
