NEWTON’S LAWS OF MOTION WEBQUEST NAME: __Papichaya. Jintanalert ______________________________ Class no: 13 Nickname: __Praew________________________________ Newton’s 1st Law of Motion http://teachertech.rice.edu/Participants/louviere/Newton/ http://www.physics4kids.com/files/motion_laws.html 1. What does the Newton’s 1st law say? an object at rest tends to stay at rest, and an object in motion tends to stay in motion, with the same direction and speed. Motion (or lack of motion) cannot change without an unbalanced force acting. 2. What is an unbalanced force? force applied in one direction is greater than the force applied in the opposite direction. When unbalanced forces are acting on an object, there is a change in speed and/or direction 3. What is the relationship between unbalanced forces and Newton’s 1st Law? a body at rest will remain at rest unless acted upon by an unbalanced force. 4. List 3 detailed examples that illustrate of Newton’s 1st Law. -pushing my friend Playing football Driving a car 5. Create a demonstration or illustration that shows Newton’s 1st Law.
Newton’s 2nd Law of Motion http://teachertech.rice.edu/Participants/louviere/Newton/ http://www.physics4kids.com/files/motion_laws.html 1. What does Newton’s 2nd Law say? an object produced by a net (total) applied force is directly related to the magnitude of the force, the same direction as the force, and inversely related to the mass of the object 2. What is acceleration? the rate of change of the velocity of an object with respect to time. 3. What is the relationship between acceleration and Newton’s 2nd Law? object will only accelerate if there is a net or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object - changing its speed, its direction, or both its speed and direction. 4. List 3 detailed examples that illustrate Newton’s 2nd Law. 1. Pushing a Car and a Truck 2. Pushing a Shopping Cart 4. Hitting a Ball 5. Create a demonstration or illustration that shows Newton’s 2nd Law.
Newton’s 3rd Law of Motion http://teachertech.rice.edu/Participants/louviere/Newton/ http://www.physics4kids.com/files/motion_laws.html 1. What does Newton’s 3rd Law say? every action (force) there is an equal and opposite reaction (force). Forces are found in pairs. 2. What is a force? an influence that can change the motion of an object. A force can cause an object with mass to change its velocity 3. What is the relationship between force and Newton’s 3rd Law? The third law states that for every action (force) in nature there is an equal and opposite reaction. 4. List 3 detailed examples of Newton’s 3rd Law. 1. Firing of a bullet: 2. A book lying on a table 3. During swimming, a swimmer moves ahead. The water pushes back on the swimmer as the swimmer pushes against it. 5. Create a demonstration or illustration that shows Newton’s 3rd Law.
