PPT-If the sum of external forces on an object is non-zero, the

the object is accelerating the object is not accelerating it depends If the sum of internal forces on an object is nonzero then the object is accelerating the object is not accelerating. Head Office.

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.. EQ: What causes an object’s motion to change?. A . hard kick sends a soccer ball shooting down the field toward a goal.. Just in time, the goalie leaps forward, stops the ball, and quickly kicks it in the opposite direction.. 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.. A . force. is a push or a pull. .. Many different forces act on objects around us all the time.. . If . the forces on the object are . balanced. , . then the object doesn’t move. . When two or more forces are acting on an object and they are not equal in size, we say the forces are . 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.. Can cause a change in the motion of an object.. Tug-of-War Example:. . In the pictures above, each person is pulling with a force of 50N (. N. ewtons. ).. What will happen when the person from the first picture drops out?. Standards. SPS8. Students will determine relationships among force, mass and motion. b. Apply Newton’s three laws to everyday situations by explaining the following:. Inertia. Relationship between force, mass and acceleration. Changes in Motion. Objectives:. 1. Describe how force affects the motion of an object.. 2. Interpret and construct free-body diagrams.. The Force is Strong With You. Force. is an action exerted on an object which may change the object's state of rest or motion.. What is a force?. A force is a push or a pull. . Forces make objects accelerate. What are the two general types of forces? How are they different?. Type 1: Contact Forces. Force as a result of object touching. EDEXCEL TOPIC 2 - MOTION AND FORCES (part 1) Describing Motion Average speed = distance ÷ time s = d ÷ t Speed Metre/second ( m/s) Distance Metre (m) Time Second (s) Current Ampere (A) Temperature 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.. Review: Ideas about Friction. What is friction and how does it work? . Are there bumps anywhere else besides . the surface an object moves across?. Give an example of friction from your everyday life. .
