The purpose of this activity is to demonstrate the effect of electricity upon balloons and strings. 1. Prepare your desk: Ensure your hands are dry and remove any water from the surrounding area. 2. Charge the balloon: Rub the surface of a balloon with a sock until it becomes electrically

When a bee flies through the air, it experiences friction. The air pushes, against the bee's hair, there is friction between the air and the hair, and thus the hair gains a positive electrical charge. Scientists have found out that most flowers and pollen are negatively charged. When

Electric Force (EF) exists between any objects that have an electric charge, like a child and a slide. Objects can have either a positive electric charge or a negative electric charge. If an object has a positive charge and another has a negative charge, then they are drawn towards each

When you jump out of an airplane, you experience two forces: gravity and air resistance. Gravity pulls you down towards the ground, while air resistance pushes against your body as you fall. A parachute increases your air resistance as you fall, slowing you down and allowing you to arrive to
Physics
The Gravitational Force (GF) is the force that pulls two objects towards each other. If an object has a large mass, it will pull other objects towards it. One example of GF is the earth and the moon. The earth has a way larger mass than the moon, resulting in
Physics
Force A Force is the push or pull on an object. This means that if I am hitting a rock with a stick, and it goes flying, I am applying force to the rock using the stick. Net Force or N is the sum of all the forces being applied

Units are a measurement used to describe positions, speeds, and masses of objects. In the scientific world, scientists all use the same types of units (for example, meters and kilograms) to be able to communicate accurate data to each other without any mix-ups. Frames of Reference is a fancy name
