It’s a fun way to make a complicated sounding concept easy to understand. Try this simple experiment with your kids. However, the inertia of the coin was overcome by the force of gravity. The speed of the applied force that moved the card overcame the frictional force between the note card and the coin, so the coin wasn’t moved by frictional force. In fact, when the note card was quickly removed from beneath the coin, the force of gravity acted upon the coin causing it to fall into the glass. In the second part of the experiment, the coin did not move with the note card. The coin would have stayed at rest if the frictional force had not been applied to it. Students are introduced to the concepts of force, inertia and Newtons first law of motion: objects at rest stay at rest and objects in motion stay in motion unless acted upon by an unbalanced force. The hand did not touch the coin, but the coin still moved with the note card.Īccording to Apologia’s Physical Science curriculum, “ Friction is a force that results from surfaces rubbing against one another.” The frictional force between the note card and the coin acted on the coin and that force caused the coin to move along with the note card. That applied force was the hand grasping and pulling the note card. The force overcame the inertia of the note card. Then, an applied force was applied to the note card making it move. In the first part of the experiment, both the note card and the coin had a certain amount of inertia at rest.

It will help you and your students get a good idea of what the Law Of Inertia is all about and how applied force, frictional force, and the force of gravity affect objects. Try this simple experiment to test Newton’s first law of motion. Easy and engaging Find this activity in our COMPLETE NEWTONS LAWS UNIT at 30 OFF In this activity, students will:MOVE THROUGH 7 STATIONS. Objects retain their inertia unless acted on by a force. EASY PREP Newtons First Law lab stations with EASY materials Students play with common supplies to experience one of Newtons Laws of Motion firsthand. Inertia is an object’s resistance to change in its state of motion whether at rest or moving. This is sometimes referred to as the Law of Inertia. Newton’s first law of motion states that objects at rest tend to stay at rest, and objects in motion tend to stay in motion at the same speed and in the same direction unless acted upon my an outside force. Newton, also, gave us his three laws of motion. Most people remember Sir Isaac Newton as the man who first explained gravity. This Newton’s first law of motion experiment shows just how simple. They are simple rules that tell how the universe works. So any good waiter or waitress that doesn't spill coffee when they're giving it to you understands Newton's first law of motion, the law of Inertia.Don’t be intimidated by scientific laws. When I get to your table I've got a, I'm in a constant motion and I stop and put it on your table, that coffee wants to keep moving and it's going to splash out of the cup onto your table. It's going to stay at rest and it's going to spill off the back end right. So that's what we're talking about okay this is a pretty common sense example and you can state this pretty simply as stuff wants to do with stuff was doing and any good waiter or waitress knows this practice when they fill your coffee cup, if they know Newton's first law they don't fill it all the way up right but because if I've got your coffee cup and I start to go to the table well that coffee wanted to stay at rest. If I push the ball in this direction it's going to move. The force down on the tennis ball is equaled by the force in my hand pushing up on that ball. ![]() What's an unbalanced force? Well I've got a tennis ball right here and I can apply force to it but it's not moving right it's still staying steady that's because this is isn't an unbalanced force this is a balanced force. ![]() Law of Inertia it's also called Newton's first law of motion simply stated it means an object in motion tends to stay in motion or an object at rest tends to stay at rest unless the object is acted upon by an unbalanced force.
