"The Force Table" is a simple tool for demonstrating Newton’s First Law and the vector nature of forces. This tool is based on the principle of “equilibrium”. An object is said to be in equilibrium when there is no net force acting on it. An object with no net force acting on it has no acceleration. By using simple weights‚ pulleys and strings placed around a circular table‚ several forces can be applied to an object located in the center of the table in such a way that the forces exactly cancel

Rockin Roller Coaster Research Project By: Stephen Morris Period: 4th The batman rollercoaster is an extreme‚ thrilling rollercoaster. The batman rollercoaster was introduced 1997 and‚ 2‚700 feet long! The original installation of the ride is at Six Flags Great America featured a maximum height of 100 feet while the installations to follow reached 105 feet. The rides reach a top speed of 50 miles per hour and exert up to four

Although wearing your seat belt is one of the top safety precautions when it comes to riding or driving in a car‚ accidents still occur due to people being lazy and not wanting to wear their seat belt. Drivers and passengers do not wear seat belts for tons of little reasons. Some forget to wear them‚ while others are just plain lazy and think they shouldn’t have to put on seat belts. After some time‚ this becomes a really bad habit. Accidents can happen. Some may be small accidents‚ and some may

FRICTION Friction is necessary for walking due to the following reason‚ As per Newton’s third law of motion‚ (every action has an equal and opposite reaction) we can walk if and only if the ground we are walking on push our feet back with a force. Now‚ as per the third law the ground would definitely push our feet back but if we are walking on a perfectly smooth ground which has no friction our force would simply cancel out the force reverted by the ground and we would fall. If there was no

IB Friction Lab Write Up 3. The slope of my graph represents the constant value for myu as the Normal Force and the force of friction are constantly changing. 4. The kinetic slope is the biggest by far because it represents the less coefficient of friction it has to overcome to move easier. 5. According to my data table‚ an increase in weight always‚ without fail‚ creates a greater force of friction. 6. An increase in weight does not affect the coefficient of friction by also increasing

Analyzing Exploding Carts - Lab Activity Objectives We will study the relationship of force and the duration of the collision. In doing so we will observe the max force experienced by an accelerating cart when it impacts another cart with a spring. A stiff spring will be used. We will collect the information through two items. We will use distance and time as information collectors. This will measure the acceleration‚ velocity‚ and position of the cart as it moves down the track. The most

Chapter 6 Describe the “coin and feather” experiment and state what the observation shows. (5M) Put a coin and a small paper disc in a glass tube (1M) Use a vacuum pump to remove the air from the tube (1M) Hold the tube vertically then invert it quickly. (1M) The coin and the paper disc fall at the same rate (1M) The experiment shows that objects with different masses fall at the same rate when there is no air resistance. (1M) How can you find the height of a building if you are given
