- Hello Everyone!I'm PhoebeI'm here to talk about the "Law of Motion"by Sir Isaac Newton
- Meet Mr. Newtoon. Sir Isac Newtoon's three laws of motion describe the motion of massive bodies and how they interact. He was one of the most influential scientists of all time. His ideas became the basis for motion physics. Let's go everyone.
- Hello Everyone! Nice to meet you all,Let's learn something about the "Law of Motion".
- This simply means that things cannot start, stop, or change direction all by themselves. It takes some force acting on them from the outside to cause such a change. This property of massive bodies to resist changes in their state of motion is sometimes called inertia.
- External Force
- First Law of Motion. The first law of motion states, "a body at rest will remain at rest, and a body in motion will remain in motion unleess it is acted upon by external force.
- Object at Rest
- This is written in mathematical form as F = ma, where F is force, m is mass, and a is acceleration. The bold letters indicate that force and acceleration are vector quantities, which means they have both magnitude and direction.
- FORCE
- The Second Law of Motion describes what happens to a massive body when it is acted upon by an external force. It states, "The force acting on an object is equal to the mass of that object times its acceleration."
- ACCELERATION
- This law describes what happens to a body when it exerts a force on another body. Forces always occur in pairs, so when one body pushes against another, the second body pushes back just as hard.
- And lastly The Third Law of Motion states, "For every action, there is an equal and opposite reaction."
- ACTION
- REACTION
- The three laws have been verified by countless experiments over the past three centuries, and they are still being widely used to this day to describe the kinds of objects and speeds that we encounter in everyday life.
- Thank you Sir Isaac Newton. We learned something new today.Thank you everyone for your time.
- That's all for today.I hope you learn something to our simple discussion.Thank you!
