When an object is in motion, such as a falling pencil, it posseses energy, there fore something must absorb it's energy to stop it to a rest. (example- a car in motion stops by the brAke absorbing it's energy). But energy is never destroyed or created, it can only be transferred from one form to another (example- the cars brakes heat up when used because the cars energy is being transferred to heat energy). So, the instant the falling pencil strikes the ground, it stops
falling correct? But the energy the previously falling pencil possess must be transferred to another form of energy the energy can't be
"lost" right? So what happens is some of the energy is converted to heat when it strikes the ground, you may not believe it but there is heat when it hits the ground because of friction. Furthermore, some of the energy is also converted to sound energy. (the pencil makes a sound when it hits the ground and sound is energy) but the heat and the sound energy combined is not enough to transfer all of the energy of the falling pencil. So where does this little extra energy go? You guessed it! Back up! It hits the ground, it goes back up because not all of it is transferred to another form such as sound or heat so it must go back up- or as you said, bounces. Hope this helped you understand.
newton first law of motion newton second law of motion newton third law of motion newton gravitation law of motion
he discovered both because whilst discovering gravity he soon found the motion of the apple that fell to the ground
Isaac Newton formulated the laws of motion. These should not be confused with the laws of planetary motion by Keplar
it a motion of newton
newton. newton. newton.
Newton got the idea of forces from change in motion, acceleration. Aristotle had the idea no force no motion, Newton recognized inertial motion without force.
laws of accelerated motion and falling bodies
Newton used Galileo's study of motion to develop his first law of motion.
Newton was studying nature and force and motion desscribe nature.
Newton has three laws of motion.
The application for Newton's law is motion. There are several laws of motion that were defined by Isaac Newton.
Isaac Newton described three laws of motion.
Newton defined three Laws of Motion. An example is "An object in motion will remain in motion unless an external force acts upon it. "
Who supported and assisted Newton in producing his famous work on motion. ( The Principia).
They have his name on them. True, but he was proceeded by several others before him who laid the ground work.
the laws of motion the laws of motion
Sir Isaac Newton came up with the Three Laws of Motion
Issac Newton wrote "Newton's 3 Laws of Motion", which means he studied motion.
Newton invented the three laws of motion.
Newton invented his laws to describe motion.
Sir Isaac Newton did write the laws of motion.
Sir Isaac Newton discovered motion and so invented the "Laws Of Motion".
