"This book focuses on a range of programming strategies and techniques behind computer simulations of natural systems, from elementary concepts in mathematics and physics to more advanced algorithms that enable sophisticated visual results. If net unbalanced force acting on an object is zero, the object is said to be at rest. friction. Some forces, like gravity and friction, resist or work against movement. Which of the following statements does NOT describe force? speed. What can cause an object to move?? Force can cause motion in a stationary object. c). By applying an unbalanced force, you can change the motion of an object. When Σ F = 0, there is no change in motion, no acceleration. Not all forces cause motion, however. how opposite magnetic fields cause physical objects to actually move (either together or away from each other). the resistance of an object to change in its state of motion. A vibrant new voice . . . a modern classic. Unbalanced forces are the things that make objects speed up or slow down. Everytime the motion of an object changes, it's because a force has been applied to it. Unbalanced forces can also stop a moving object. Velocity is a vector, meaning it has both a magnitude (speed) and direction. Circular motion is caused by - unbalanced forces. a still object to move. Notice that because there is a bigger force and a smaller force involved, the direction of the wagon will be determined by the bigger force. Type a slash (/) if you want to This law is called the law of inertia. its mass and velocity.
