Physics Quiz on Energy and Motion

Based on the given table below, which type of engine has the least exhausted energy?

• Diesel Engine

• Gasoline Engine

• Steam Engine

• Steam Turbine

While enjoying a bowl of hot soup, you notice that the heat spreads evenly throughout the liquid, even though you only stirred it gently. This observation makes you think about the different ways heat can transfer. Which method of heat transfer is only possible in fluids like liquids and gases?

• Conduction

• Convection

• Radiation

• All of the above

You touch a metal spoon that has been sitting in a hot cup of coffee. The spoon feels warm, making you wonder about the movement of thermal energy. What happens to the thermal energy when two objects at different temperatures are in contact?

• It remains the same.

• It transfers from colder to hotter object.

• It transfers from hotter to colder object.

• It transfers from hotter to colder object until thermal equilibrium is achieved.

Imagine you are using a piston to compress a gas while adding heat to it. You wonder how the gas's internal energy changes when the heat added (Q) equals the work done (W). What happens to the internal energy when both heat transfer (Q) and work done (W) are equal?

• The internal energy has no net change and is not affected.

• The internal energy is equal to the difference of heat and work.

• The internal energy is equal to the sum of heat and work.

• The internal energy remains the same.

While studying thermodynamics, you analyze a situation where a gas does 400 J of work on its surroundings, and 900 J of heat is added to the gas. You need to determine the change in the internal energy of the gas. What is the change in the internal energy of the gas?

• 300 J

• 400 J

• 500 J

• 900 J

You learn about different sources of energy and wonder where geothermal energy, a renewable resource, originates. Where does geothermal energy come from?

• Heat from the Earth

• Rivers

• Sunlight

• Wind

You visit a geothermal power plant and see how hot water and steam from deep underground are used. You consider the purpose of this energy conversion. Geothermal power plants can generate ___________ by using hot water and steam from deep in the Earth.

• Air conditioning

• Electricity

• Greenhouse gases

• Hydropower

Imagine you kick a soccer ball, and it follows a curved path through the air before landing. You consider the types of motion involved. Which of the following composed the two linear motions of a projectile?

• Horizontal and Circular Motion

• Horizontal and Vertical Motion

• Vertical and Circular Motion

• Vertical and Curvilinear Motion

You throw a rock upward, and after reaching its highest point, it falls back down solely due to gravity. You wonder how this kind of motion is classified. What is called an object given an initial velocity and then acted solely on by gravitational force?

• Project

• Projectile

• Target

• Trajectory

While watching a basketball game, you notice the curved path of the ball as it arcs toward the hoop. You think about what this path is called. What do you call the path followed by a projectile?

• Project

• Projectile

• Target

• Trajectory
