KINETIC ENERGY AND POTENTIAL ENERGY

What is the magical formula for unlocking Kinetic Energy?

• KE = 0.5 * mass + velocity^2

• KE = 0.5 * mass * velocity

• KE = mass * velocity^2

• KE = 0.5 * mass * velocity^2

What is the super cool rule that says energy can't be created or destroyed, only changed from one form to another?

• Energy can be destroyed and created at will

• Energy cannot be created or destroyed, only transferred or converted from one form to another.

• Energy is only conserved in closed systems

• Energy conservation is not a fundamental law of physics

What is the magical formula for calculating Gravitational Potential Energy?

• GPE = mgh + 2

• GPE = mgh

• GPE = mgh^2

• GPE = mgh / 2

Imagine a superhero flying with a speed of 5 m/s and weighing 2 kg. What would be the explosive Kinetic Energy?

• 10 Joules

• 20 Joules

• 25 Joules

• 15 Joules

What happens to the balance between Kinetic Energy and Potential Energy in a system?

• Kinetic Energy and Potential Energy like to play hide and seek with each other

• Potential Energy throws a surprise party for Kinetic Energy

• As Kinetic Energy puts on a show, Potential Energy takes a break, and vice versa

• Kinetic Energy and Potential Energy dance together in perfect harmony

Imagine a 10 kg object magically lifted to a height of 5 meters. What is the Gravitational Potential Energy of this object?

• 490.5 J

• 550.5 J

• 510.5 J

• 450.5 J

What is the relationship between work and kinetic energy?

• Work and kinetic energy are completely unrelated concepts

• Work done on an object is equal to the change in its kinetic energy

• Work decreases kinetic energy and increases potential energy

• Work is only related to potential energy, not kinetic energy

What is the unit of measurement for energy?

• Watt

• Joule

• Newton

• Ohm

How does friction affect the conservation of mechanical energy in a system?

• Friction has no impact on the conservation of mechanical energy

• Friction increases the mechanical energy of the system

• Friction decreases the mechanical energy of the system

• Friction converts mechanical energy into thermal energy

What is the unit of measurement for power?

• Watt

• Joule

• Newton

• Ohm
