FORCE AND MOTION FULL

This is a standard international system of a unit (SI unit) which is expressed in Newton (N). These are the units of force that explain how force is measured. So, it is obvious what is the unit of force. unit of force, we have to know about Sir Issac Newton who first studied gravity and force. Based on Newton’s universal law of gravitation every object in this universe exerts a force on other objects. This mainly happens when two entities come in contact. Similiar to push and pull, words like squeeze and stretch also explains the concept of what forces can do. The push and pull acting on an object or energy as a movement or attribute of physical activity is defined as forced. To comprehend what is force, we have to think in terms of pull and push. To figure out this relationship existing between force and motion we have to understand the terms individually. A force causes interaction between two or more bodies and when that remains unobstructed generates a change in the state of motion. For example, the interdependence of force and motion can be viewed from the perspective of throwing a ball and catching it back. In general physics, the term force and motion are interrelated and are two sides of the same coin. Do you know what causes and obstructs motion in the body or object? The answer is the application of force.

Walls keep falling down: If you need help getting your wall to stay up, clip the 1-inch fold on the back to a clipboard, or slide it under the edge of a heavy book.There are different types of motion related to the human body.

If the lock is getting stuck because a piece of paper is bending the wrong way, you can make the paper stiffer by folding it and adding stickers or paper clips to hold it together.

If your lock keeps getting stuck, try rounding the edges of the moving parts.

Pieces keep getting stuck against one another: If it’s attached too tightly, your magnet may not be able to move it.

If a piece of your lock is supposed to move, be sure it can move easily. The magnet doesn’t make the lock move: Every lock will work differently, but it’s typically friction that causes this problem.

Twist the brad in a full circle a few times to enlarge the hole. Items won’t turn on the brad: The hole probably isn’t big enough. If this happens, use a sharp pencil to poke a small hole in the paper, then insert the brad. Below are some of the more common difficulties we found during our own testing, and the solutions we came up with.īrads won’t puncture paper: Students may have trouble puncturing the paper with the brad. In this activity, students are asked to create something new - an essential part of the engineering process, but one that may confuse or frustrate them. You may want to sort your materials into two piles for easier distribution. Then, students will design a lock for their door using a magnet, paperclip, paper fastener, stickers, and index cards. The Teacher Tips printout will help you guide students during this open-ended exploration.Įach student will first make a paper door using cardstock, scissors, and a post-it note.

For this open-ended exploration, you can supply students with extra chipboard, extra rubber bands of different sizes, or extra rubber bands of different thicknesses. Supplies for Open-Ended Exploration (Optional)Īt the end of the activity, we suggest that students change one variable to see how this affects their Hopper Popper. It doesn’t take long if you use a paper cutter.

If you don’t have time for students to measure and cut rectangles, we recommend you cut the chipboard into 3” x 6” rectangles before class. If you want your students to practice measuring, you can have them cut 3” x 6” rectangles from chipboard before you begin this lesson. Some teachers choose to have students wear safety glasses for this activity since Hopper poppers can hop high! Prepare the Chipboard Homeschool students can work on their own, but may need a partner to help when it comes time to launch their Hopper Popper. In this activity, each student will make their own Hopper Popper, but we suggest they work in pairs when they launch their poppers.
