Energy the ability to do work or cause change Kinetic Energy energy an object has due to its movement Abrasion wearing away of rock by a grinding action Load the amount of sediment that a river carries. On a post-it, write down anything you know about the word force or the different ways you use the word force.. Scientific Definition. A force is a . push . or a . pull. of an object.. When there is a force, one object is applying a force and on object is receiving the force.. Forces act on you all the time. . If . you surf, you can feel many forces pushing and pulling you in different directions. . Gravity . always pulls you down, towards planet Earth. . This . force can be balanced by the support of the surfboard acting upwards. . Rate Yourself. 4 = . Explain real world situations using academic voc. . a. nd Newton’s laws.. 3 . = . Investigate and describe types of forces. Differentiate between mass and weight.. 2 . = . Describe the relationship between distance, mass, and gravitational force.. 11.1: Forces change motion. 11.2: Force and mass determine acceleration. 11.3 Forces act in pairs. 11.4 Forces transfer momentum. Warm-up Questions (T or F). Speed includes direction, while velocity does not. A force is a push or a pull on an object. Every force has strength, magnitude and direction.. Forces acting on a stationary object can set the object in motion. . They can also change the object’s speed or the direction it is moving in.. Forces felt in . - and . -fields. Motion of particle in a . -field. Applications.  . Charges set up an . electric field . , in which other charges feel an . electric force. Currents (or magnets) set up a . Velocity (v) . is the rate at which an object is changing position per unit of time with a direction.. Direction is: . north, south, east, west, right, left, up, down.. Velocity changes. when one or both of the following change: . CHAPTER 19. M. OSTMANN. 7. th. Grade Science. Kate Bond Middle School. WHAT IS A FORCE?. What causes these cyclists to move forward?. What prevents these cyclists from moving as fast as a race car?. Define . forces and different types of forces (push or pull). Measuring . forces in Newtons. Balanced . vs unbalanced forces. Inertia- . what is it and how does it apply to Newton’s first law of motion.. . . Example:. What is a force? . a) Strong . nuclear . force. b) Electromagnetic force. c) Weak force. d) Gravity.. EXAMPLE? an atom . #2) There are four forces that hold all matter together. 3) Gravitational forces . Force. - a . push. or . pull . A . Force . 1. gives. . energy . to objects. 2. causes a. . change . in motion, such as:. . Starting. Speeding Up. Changing Direction. Stopping. Slowing Down. (Note: all of these are forms of . Newton. The measurement of force. *You can measure force using the spring scale at a grocery store.. *A force is measured in . newtons. .. *one newton is equal to one kilogram meter per second squared. Types of . Forces. :. Push. Pull. Friction. Air Resistance/Drag. Buoyancy/. Upthrust. Gravity. Twist. Elastic/stretch. Static Electricity. Magnetism. Reaction . A force is a . push. or . pull. on an object.. Essential Question:. How do gravity, inertia, and friction affect the balance of forces?. Standard:. S8P3b. Demonstrate the effect of balanced and unbalanced forces on an object in terms of gravity, inertia, and friction.
