⚙️ Springs can appear to defy gravity due to the tension in the spring counteracting the force of gravity, especially noticeable when a longer spring is used.

Q & A

What causes high and low tides on Earth?
-High and low tides on Earth are caused by the gravitational forces exerted by the moon and the sun. The moon's gravity pulls the oceans towards it, creating a high tide on the side of Earth nearest to the moon and another high tide on the opposite side. The sun also affects tides but to a lesser extent due to its greater distance from Earth.
How can you separate salt from pepper using static electricity?
-You can separate salt from pepper using static electricity by charging a plastic spoon negatively with static electricity, by rubbing it on a cloth. When brought near a mixture of salt and pepper, the lighter pepper particles, which are more affected by static forces due to their lighter weight, will jump to the spoon, leaving the heavier salt particles behind.
What role does gravity play in affecting the depth of water around Earth?
-Gravity plays a crucial role in affecting the depth of water around Earth. Without gravity, water would be distributed evenly around Earth's surface. However, the gravitational forces from the moon, and to a lesser extent the sun, cause variations in water depth, leading to the phenomenon of tides.
What is an endothermic reaction and how does it relate to cooling a drink with salt and ice?
-An endothermic reaction is a chemical reaction that absorbs heat from its surroundings. When salt is added to ice, it lowers the freezing point of water and causes the ice to melt, absorbing heat in the process. This makes the mixture colder, which can then be used to more effectively cool a drink.
How does building material and soil type affect the stability of buildings during an earthquake?
-The stability of buildings during an earthquake is significantly influenced by the type of soil and building materials used. Buildings on solid, non-moving soil are more stable, whereas those on soft or shaky soil are more prone to damage. Additionally, different materials can absorb or amplify the seismic energy differently, affecting the building's ability to withstand shaking.
What experiment demonstrates the effects of static electricity on small particles like salt and pepper?
-An experiment that demonstrates the effects of static electricity involves using a negatively charged plastic spoon to attract and separate pepper from salt. The lighter pepper particles are more susceptible to the static charge and are lifted away from the heavier salt particles.
How does the alignment of the moon and sun affect the severity of tides?
-The alignment of the moon and sun significantly affects the severity of tides. When the sun and moon are aligned (during new and full moons), their gravitational forces combine to produce spring tides, which are higher and lower than average. When they are at right angles to each other (during quarter moons), they produce neap tides, which are less severe.
What is the principle behind using a hover disc to reduce friction?
-The principle behind using a hover disc involves creating a cushion of air beneath the disc by expelling air through a central hole. This air cushion reduces contact with the surface, thereby significantly reducing friction and allowing the disc to glide smoothly over the surface.
Why are potato chip bags filled with air?
-Potato chip bags are filled with air primarily to protect the chips from being crushed during transportation and handling. The air acts as a cushion, absorbing impacts and maintaining the integrity of the chips inside the bag.
What scientific concept explains why a spinning top remains upright while in motion?
-The scientific concept that explains why a spinning top remains upright while in motion is angular momentum. Angular momentum stabilizes the top, preventing it from tipping over due to the conservation of angular momentum, which keeps the top spinning around its axis.
