Fill In The Blanks With Correct Terms Of Physics Quiz

When an object is moving at a constant velocity, it means there is no change in speed or direction, resulting in zero acceleration according to Newton's First Law of Motion.

Vector quantities have both magnitude and direction, while scalar quantities have only magnitude.

Newton's First Law, also known as the Law of Inertia, states that an object will remain in its state of rest or motion unless acted upon by an external unbalanced force. This means that objects will continue their motion or lack of motion unless a force is applied to change that state.

Newton's Third Law states that for every action there is an equal and opposite reaction. This means that whenever one object exerts a force on another object, the second object exerts an equal force in the opposite direction.

Copernicus proposed the heliocentric model, where the sun is at the center of the solar system and not the earth. This was a significant shift from the previously widely accepted geocentric model.

The correct answer is 'Prettier' as it completes the sentence making a comparison about physical appearance.

When an object is thrown horizontally at a velocity of at least 8 km/s (equivalent to 18,000 mph), it will achieve escape velocity and not fall back to Earth due to the gravitational pull. This is a key concept in understanding orbital mechanics and space travel.

When a car turns a corner, friction between the tires and the road provides the centripetal force necessary to keep the car moving in a circular path.

The 'American' unit of power, horsepower, is commonly used to measure the power of engines, particularly in the automotive industry.

Energy is defined as the ability to do work, which involves applying a force to move an object over a distance. The incorrect answers listed do not accurately describe the concept of energy in the context of physics.

An object is stable when its center of mass stays above its base of support. The base provides stability by preventing the object from tipping over.

Gravity is the force of attraction between objects with mass. It is responsible for the motion of planets around the Sun in their respective orbits. The other options do not accurately represent the force that keeps planets in their orbits.

When you double your speed, your stopping distance increases by a factor of 4 due to the relationship between speed and stopping distance being quadratic.

Johannes Kepler's mother, Katharina Kepler, was tried for witchcraft during the infamous witch trial era in Europe.

Power is measured in watts, not joules, volts, or ohms. Joules are units of energy, volts measure electrical potential difference, and ohms measure electrical resistance.

Kepler's First Law states that the orbit of each planet is an ellipse with the Sun at one of the two foci. This law describes the shape of planetary orbits in our solar system.

Atmospheric pressure typically ranges around 14.7 lb/in2 at sea level. 15 lb/in2 is a common rounded value used to represent atmospheric pressure in everyday calculations.

In the nucleus of Carbon-14, there are 6 protons and 8 neutrons. The total number of neutrons can be calculated by subtracting the atomic number from the mass number.

According to Boyle's Law, when pressure is doubled, the volume of a gas decreases to half. This is because the relationship between pressure and volume of a gas is inversely proportional when the temperature and amount of gas are constant.

A barometer is specifically designed to measure atmospheric pressure, while a thermometer measures temperature, a hygrometer measures humidity, and an anemometer measures wind speed. Thus, the correct answer is 'Barometer'.

Bernoulli's principle explains the lift generated by airplane wings, the operation of carburetors in engines, and how fireplaces draw smoke up the chimney. Water skiing, however, is a surface water sport that does not directly involve the principles of fluid dynamics explained by Bernoulli's principle.

The correct number of electrons in neutral Uranium 235U-92 is 92, which corresponds to the atomic number of uranium.

When the temperature of a gas in a fixed volume container is increased, the gas particles gain more kinetic energy, causing them to collide with the walls of the container more frequently and with greater force, resulting in an increase in pressure.

Heat transfer through radiation involves the emission of electromagnetic waves, while conduction and convection require a medium such as a solid, liquid, or gas for the transfer to occur. Insulation is a material used to reduce the transfer of heat through conduction or convection.

In this context, convection refers to the transfer of heat through the movement of a fluid (liquid or gas). While radiation and conduction are also methods of heat transfer, they do not involve the movement of a fluid as convection does. Insulation, on the other hand, refers to materials that are used to reduce heat transfer rather than facilitate it through fluid movement.

Conduction is the process of heat transfer between two objects that are in direct contact with each other. Convection involves the transfer of heat through the movement of liquids or gases. Radiation is the transmission of heat through electromagnetic waves. Insulation is a material that is used to reduce the transfer of heat.

Temperature is a measure of the average kinetic energy of the molecules in a substance. The motion of the molecules contributes to their kinetic energy, which in turn determines the temperature of the substance. Mass, volume, and density are properties of substances that are not directly related to temperature as it specifically refers to the average kinetic energy of molecules.

The British Thermal Unit (BTU) is a non-metric unit used to measure heat. It is commonly used in the United States. Joule, Calorie, and Kilowatt-hour are metric units of heat and energy measurement.

Water boils at 212 degrees Fahrenheit (100 degrees Celsius) at standard atmospheric pressure. Any other temperature options provided are incorrect in the context of boiling water.

When a gas expands, it does work against its surroundings which causes it to lose energy. This energy loss results in a decrease in temperature according to the ideal gas law.
