What Is Newton S Second Law of Motion? Virtual Lab

<p> What is Newton’s Second Law of Motion? Virtual Lab http://www.glencoe.com/sites/common_assets/science/virtual_labs/E25/E25.html</p><p>______is a ______or ______on an object. ______force is the ______between ______forces. ______second law of ______states that if a net ______acts on an ______, the ______will ______in the ______of the ______. ______is a ______in ______. It can be either ______(______up) or ______(______down). </p><p>If an ______is not ______, the net ______on it must be ______. A ______that we all ______is ______. A notebook ______on a desk is being ______by the ______of ______. At the same time, it is being ______by the ______of the ______. The ______of ______is ______to the ______of the ______, so the ______on the notebook is ______. If an elbow ______the notebook off the desk, the ______of the ______is ______longer ______by the ______of the desktop, and the notebook ______as it ______to the ______.</p><p>The formula for calculation a force on an object is F = ma.</p><p> F= force  m= mass  a= acceleration</p><p>______is the ______of ______contained in an object. ______does ______change with ______in ______. In the previous example, F refers to the ______of ______on the notebook, also known as its ______; m is the ______of the notebook; and a is the ______of the ______caused by the ______of ______.</p><p>The ______of any object ______to the ______of Earth is 9.8 ______per ______per ______, or 9.8 m/s2. This means that at the first ______, the ______will be ______with a ______of 9.8 m/s2. At 2 ______, the object will be ______at the ______of 19.6 m/s2; at 3 ______, it will be falling at the rate of ______, and so on.</p><p>If the ______of the notebook is ______, and the ______is ______, the ______(______) of the notebook can be calculated using the ______F= ma: F= 0.5 kg x 9.8 m/s2= 4.9 The ______(N) is the ______used to ______an ______of ______. In the example above, F= 4.9 N. Therefore, 4.9 kg m/s 2 = 4.9 N</p><p>In this virtual lab you will investigate the relationship between mass, acceleration, and force by experimenting with falling objects of various masses under a range of gravitational conditions.</p><p>Objectives:  Relate Newton’s second law of motion to the effect of gravity on falling objects.  Determine the effect of mass on the acceleration rate of falling objects.  Observe the effect of gravitational conditions on the rate at which objects of identical mass fall.  Given mass and acceleration, compute force.</p><p>Follow the procedure to complete the lab, chart, and questions.</p><p>Chart: Gravitational Acceleration, Mass, and Weight Test/Location Accelerati Object Mass of Weight of on (m/s2) Object (kg) Object (N) 1 Location 1 Location 2 2 Location 1 Location 2 3 Location 1 Location 2 4 Location 1 Location 2 5 Location 1 Location 2 6 Location 1 Location 2</p><p>Questions: 1. According to Newton’s second law of motion, a net force on an object will cause it to accelerate. How does the Newton’s law relate to the force of gravity?</p><p>2. How does the force of gravity affect the rate of acceleration? 3. Describe what happens when identical objects are dropped under different gravitational conditions.</p><p>4. Describe what happens when objects of different mass are dropped under same gravitational conditions.</p><p>5. What is weight? What is mass? How are mass and weight different?</p><p>6. Based on your experience with the experiments, how does mass affect weight?</p><p>7. What other conclusions can you draw from the data you collected in your table?</p>
