How to Use the Forces and Motion PhET Simulation Lab

The Forces and Motion PhET Simulation Lab is an interactive online tool that allows you to explore the effects of different forces on the motion of objects. You can use this lab to learn about Newton's laws of motion, friction, net force, balanced and unbalanced forces, and more. In this article, we will guide you through the steps to use the lab and answer some questions along the way.

Getting Started

To access the lab, go to this page: https://phet.colorado.edu/en/simulation/forces-and-motion-basics. You will see two tabs: Tug of War and Motion. Click on the Tug of War tab to start.

Tug of War

In this tab, you can create a scenario on the rope pull in which the forces are balanced or unbalanced. You can drag different characters onto the rope and adjust their applied force by moving the slider. You can also check the boxes in the upper right corner to show the force vectors, values, masses, and net force.

Question 1: Create a scenario on the rope pull in which the forces are balanced. Draw a picture of the vector arrows and the net force arrow in the space below. What is the net force on the cart

Answer 1: One possible scenario is to have two people on each side of the rope with equal applied force. For example, you can drag two kids on each side and set their force to 50 N. The vector arrows will be equal in length and opposite in direction. The net force arrow will be zero. The net force on the cart is zero.

Question 2: Create a scenario on the rope pull in which the forces are unbalanced. Draw a picture of the vector arrows and the net force arrow in the space below. What is the net force on the cart

Answer 2: One possible scenario is to have more people or stronger people on one side of the rope than the other. For example, you can drag two adults on one side and one kid on the other side. The vector arrows will be unequal in length and opposite in direction. The net force arrow will point towards the side with more or stronger people. The net force on the cart is equal to the difference between the applied forces. For example, if one adult has 100 N of force and another has 150 N of force, and the kid has 50 N of force, then the net force is 200 N - 50 N = 150 N.

Motion

In this tab, you can create different scenarios involving objects on a surface with or without friction. You can drag different objects onto the surface and apply a constant or variable force to them by using a pusher or a fan. You can also check the boxes in the upper right corner to show the force vectors, values, masses, speed, acceleration, sum of forces, friction coefficient, normal force, applied force, friction force, and gravity.

Question 3: How does the presence of friction affect the movement of the objects in

the simulation

Answer 3: Friction is a force that opposes motion between two surfaces that are in contact. When there is friction, it reduces

the speed and acceleration of an object that is moving or trying to move. When there is no friction, an object will keep moving at a constant speed unless another force acts on it.

Question 4: Before

the object starts moving, what do you notice about

the friction force and

the applied force (Are

the forces balanced or

unbalanced)

the object starts moving,

the friction force and

the applied force are equal

and opposite. The forces are balanced

and there is no net force

on

the object.

Question 5: After

the object starts moving,

the friction force and

the applied force (Are 9160f4acd4
