Newton's laws of Force and Motion...pptx

This powerpoint presentation can help the students to study about the three laws of motion and how they are related to the different daily activities that surround us as well as forces of nature.

1. FORCE

2. - LO MOTION

3. FORCE & MOTION

4. FORCE Interaction between two objects that causes a change in the motion of the objects. What impact can forces have on objects? make it move make it speed up make it slow down stop it cause it to change direction cause it to change shape In what way does the mass of an object impact force?

5. FORCE How do Newton’s laws of motion explain the way bodies move? Aristotle initiated the study of motion during the fourth century B.C. He believed that a body will keep moving as long as a force is applied on it.

6. FORCE How do Newton’s laws of motion explain the way bodies move? Galileo Galilei opposed Aristotle’s idea. In his inclined plane experiments, He showed that when an object starts moving down an incline, it continues its motion even without the application of force. Galileo referred to this property of an object as inertia. Later on, Newton refined Galileo’s idea of inertia and formulated his three laws of motion.

7. Types of 1. CONTACT FORCES NORMAL FORCE FRICTION FORCE TENSION FORCE 2. NON-CONTACT FORCE GRAVITATIONAL FORCE ELECTROMAGNETIC FORCE FORCE

8. CONTACT FORCE NON-CONTACT FORCE Objects can be moved and made to interact with each other through action. requires two objects to be in physical contact with one another typically caused by physical objects, such as when two objects rub against one another typically localized and affects only the two objects that are in contact acts upon objects without physical contact typically caused by energy, such as light, sound, and magnetism can affect multiple objects at once

9. ISAAC NEWTON? WHO WAS A renowned physicist and mathematician from England who discovered in 1687 the correlation between force and motion. Today, his three laws of motion are instrumental in describing the movement of any object in the universe.

10. FIRST LAW OF MOTION NEWTON'S States an object at rest will stay at rest unless acted on by an unbalanced force. An object in motion will stay in motion at the same speed and in the same direction unless acted on by an unbalanced force. Law of Inertia

11. SECOND LAW OF MOTION NEWTON'S States the acceleration of an object by a force is inversely proportional to the mass of the object and directly proportional to the force. FORCE = MASS • ACCELERATION Law of Acceleration

12. THIRD LAW OF MOTION NEWTON'S States for every action, there is an equal but opposite reaction. Law of Interaction

13. Can you think of scenarios where Newton's Third Law of Motion is relevant? Name instances where Newton's First Law of Motion comes into play. Provide examples of when Newton's Second Law of Motion is applied.

14. MOMENTUM The measure of an object’s resistance to changes in its state of motion due to the application of a force. Momentum = mass • velocity Momentum = mass in motion p = m • v

15. CONSERVATION OF MOMENTUM A scientific principle that states that the total momentum of a system, or group of objects, remains constant if no external forces act upon it. This principle applies to objects in motion. It is closely related to Newton's Third Law of Motion which states that for every action, there is an equal and opposite reaction. m1v1 + m2v2 = (m1 + m2)v

16. CONSERVATION OF MOMENTUM IN ONE DIRECTION CONSERVATION OF MOMENTUM IN TWO DIRECTIONS When two objects interact in a single direction, the total momentum of the two objects before the interaction is equal to the total momentum after the interaction. If two objects interact in two perpendicular directions, the total momentum of the two objects before the interaction is the same as the total momentum after the interaction in both directions.

17. IMPULSE When a force is applied to an object, it will result in a change of momentum. This change may involve a shift in velocity, such as an increase or decrease in speed, or a change in direction. Impulse = Momentum Change An impulse causes a momentum change F • ∆t = m • ∆v

18. INERTIA ACCELERATION The tendency of an object to resist a change in motion. This means that an object will either stay at rest or continue moving in a straight line at a constant speed. The change in the speed or direction of an object’s movement. Acceleration = Change in Velocity / Time

19. Answer this! Direction: Sort the following forces into contact or non-contact force Gravitational Force Normal force Magnetic force Electromagnetic force Friction force CONTACT FORCE NON- CONTACT FORCE
