Physics of Rolling Ball Coasters
... When using physics to determine values like acceleration, there are often two perfectly correct approaches: one is using energy (like we just did), and a second is by using forces. While energy is often simpler computationally, it is not always as satisfying. For this next situation, the previous ap ...

Essential Question
... An object will have greater acceleration if a _____________ force is applied to it. An object with less mass will accelerate faster. An example of Newton’s Second Law of Motion: A baseball and a bowling ball are both hit with the same bat and the same force. The baseball will have a greater acce ...

Newton`s Laws of Motion - CEC
... Now let’s introduce the second part of Newton’s first law, which is that objects in motion tend to stay in motion until something hits them. An example of this is what happens if an astronaut throws something while in outer space. The item will continue in the same direction and at the same speed un ...

Circular Motion
... When an object moves in a circle, the net force toward the center of the circle is called the centripetal force To analyze centripetal acceleration situations accurately, you must identify the agent of the force that causes the acceleration (such as tension on a string). Then you can apply Newton’s ...
