PPT-Force and Motion

1 What is Physics Study of the nature of the Universe what the Universe is made of Matter stars and planets and galaxies different forms like gases and liquids and solids subatomic particles like protons and electrons. Chapter 2 Section 2 Review. A. . An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.. B. . Every action has an equal and opposite reaction. . express angular displacement in radians. . understand and use the concept of angular velocity to solve problems. . recall and use . v = r. ω. to solve problems. . describe qualitatively motion in a curved path due to a perpendicular force, and understand the centripetal acceleration in the case of uniform motion in a circle. . A projectile is an object upon which the only force acting is gravity. .. An . object dropped from rest is a projectile (provided that the influence of air resistance is negligible). .  . An object that is thrown vertically upward is also a projectile (provided that the influence of air resistance is negligible). . Housekeeping. Newton’s . First Law of . Motion. Newton’s Second Law of . Motion. Newton’s Third Law of Motion. Glossary. Inertia. is the property of objects that makes them resist changes in their motion. So, the greater the mass of an object, the more inertia it has. For example, it takes a much . U2L2. 2. Lesson 2 Key Question. Example: Consider giving a low-friction cart a quick shove along a track.. When an object is moving, does this mean there must be a force pushing it in the direction of its motion?. 1. A system of objects that are not moving with respect to one another. Used to determine the motion of an object.. Frame of Reference. 2. If you were measuring the length of a lunch tray you would most likely label it with the following unit.. 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. What is motion?. Motion . is . when an object changes its . position. .. Motion . can be represented mathematically through calculations of . speed, velocity, and . acceleration. Motion is . when an object changes its position. Can you change your velocity while not changing your speed?. v. F. Consider the above situation.. According to Newton . S. econd law, what must the object be doing?. It is accelerating so the velocity must be changing.. Physics. Coach Taylor. Broad Run High School 2010-2011. Objectives. Recognize that the vertical and horizontal motions of a projectile are independent.. Relate the height, time in the air, and initial vertical velocity of a projectile using its vertical motion, then determine the range.. Material on Final Exam. Section 1: Measuring Motion. Objectives:. Describe the motion of an object by the position of the object in relation to a reference point. Identify the two factors that determine speed. Forces. We have learned that forces . either pushes or pulls.. They come in many varieties:. Gravity & Normal. Kinetic & Static Friction. Electrical & Magnetic. Air resistance. Tension. Nuclear Force. Dynamics is the study of force and its effect of motion.. A force is a push or pull that can change the inertia of an object.. Newton’s First Law of Motion. Every body continues in its state of rest or motion, unless acted upon by a force.. Vocab. Energy – the ability to do work or cause change. Motion – an object’s position changes relative to another object. Force – a push or pull. Work – when the force exerted is in the same direction as the motion.
