If you need further help, What you will learn from this video What you will learn • Newton's 1st law tells us that an object won't change its motion unless acted upon by a force. • Newton's 2nd law tells us that heavier objects need a larger force to move them. • Newton's 3rd law tells us that for every action there is an equal and opposite reaction. Before Video What are some forces that cause objects to move? ANSWER • Some forces are pushes, pulls, kicks, wind and water. What happens when two objects collide? ANSWER • It depends on if the objects are moving in opposite directions or the same direction. If a car rear ends another, the first car will be pushed forward, while the second would slow down. If two cars are moving in opposite directions toward each other and collide, they would both eventually stop, and the metal of the cars would crumple. What happens when you throw something heavy vs. throwing something light? ANSWER • Heavy objects don’t go as far as lighter objects when using the same amount of force. If you use more force on the heavier object than the lighter object, you might be able to throw them the same distance. Describe a very powerful force. ANSWER • The movement of water ca...

Newton's First Law Newton's First Law of Motion Video Tutorial The Newton's First Law Video Tutorialdescribes the two claims associated with Newton's First Law and the one condition under which those claims are true. The concept of inertia is introduced. The video lesson answers the following questions: • What are the two claims and the one condition that are stated in Newton’s first law? • What does Newton’s first law mean when it comes to predicting the motion of an object? To improve the effectiveness of the learning experience, The Physics Classroom has provided the following tools: Lesson Notes The Lesson Notes are intended to be printed and used when watching the video. They are structured to allow students to follow the video, record some notes, and leave the video with a document that can be referred to as their learning continues. The Lesson Notes are available as a PDF. Permission is granted to print the notes or to include a link to them from a learning management system. View Additional and Related Learning Tools Learning takes effort. Watching a video is a relatively passive activity. It's one thing to listen to a video presented by a person who understands the material. But it's quite another thing to apply the information from the video in an effort to personally understanding the material.This page lists a variety of tools that can used to put the new learning to use. The tools include those that can be used by students and those that can be used by teacher...

\( \newcommand\) • • • • • • • • • • Learning Objectives • Describe Newton's first law of motion • Recognize friction as an external force • Define inertia • Identify inertial reference frames • Calculate equilibrium for a system Experience suggests that an object at rest remains at rest if left alone and that an object in motion tends to slow down and stop unless some effort is made to keep it moving. However, Newton’s first law gives a deeper explanation of this observation. Newton’s First Law of Motion A body at rest remains at rest or, if in motion, remains in motion at constant velocity unless acted on by a net external force. Note the repeated use of the verb “remains.” We can think of this law as preserving the status quo of motion. Also note the expression “constant velocity;” this means that the object maintains a path along a straight line, since neither the magnitude nor the direction of the velocity vector changes. We can use Figure \(\PageIndex\): An air hockey table is useful in illustrating Newton’s laws. When the air is off, friction quickly slows the puck; but when the air is on, it minimizes contact between the puck and the hockey table, and the puck glides far down the table. Newton’s first law is general and can be applied to anything from an object sliding on a table to a satellite in orbit to blood pumped from the heart. Experiments have verified that any change in velocity (speed or direction) must be caused by an external force. The idea of generall...

state of motion? The state of motion of an object is defined by its Inertia: tendency of an object to resist changes in its velocity. state of motion (i.e., velocity) unless acted upon by an unbalanced force. An object in motion with a velocity of 2 m/s, East will (in the absence of an unbalanced force) remain in motion with a velocity of 2 m/s, East. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. Objects resist changes in their velocity. As learned Inertia: tendency of an object to resist acceleration. Watch It! An air track glider is shown moving across an air track. Air is blown through many small holes in the track in order to lift the glider off the track. This reduces, maybe even eliminates, the action of surface friction upon the glider. The glider moves with what seems to be a constant speed motion. As they say: objects in motion stay in motion ... . Check Your Understanding 1. A group of physics teachers is taking some time off for a little putt-putt golf. The 15th hole at the Hole-In-One Putt-Putt Golf Course has a large metal rim that putters must use to guide their ball towards the hole. Mr. S guides a golf ball around the metal rim When the ball leaves the rim, which path (1, 2, or 3) will the golf ball follow? The answer is 2. Once leaving the rim, the ball will follow an "inertial path" (i.e., a straight line). At the instant shown in the diagram, the ball is moving to the right; once leaving the...
