Exploring the Concepts of Kinetic Energy

What is the origin of the word 'kinetic'?

• Latin

• Greek

• French

• German

In the rat family example, which piece of cheese has more kinetic energy when one is pushed twice as fast as the other?

• The slower cheese

• The faster cheese

• Both have the same kinetic energy

• It depends on the type of cheese

When Papa Rat sends back a piece of cheddar and a piece of Swiss at the same speed, which has more kinetic energy?

• The cheddar

• Both have the same kinetic energy

• It depends on the speed

• The Swiss

If the Swiss cheese is moving twice as fast as the cheddar, which has more kinetic energy?

• The cheddar

• It depends on their masses

• Both have the same kinetic energy

• The Swiss

What does the kinetic energy equation depend on?

• Only mass

• Only speed

• Neither mass nor speed

• Both mass and speed

In the kinetic energy equation, what is the role of velocity?

• It is halved

• It is not included

• It is squared

• It is cubed

What happens to kinetic energy if an object's speed doubles?

• It remains the same

• It quadruples

• It triples

• It doubles

Calculate the kinetic energy of a 0.1 kg cheddar moving at 2 m/s.

• 0.1 joules

• 0.2 joules

• 0.4 joules

• 0.8 joules

When the Swiss cheese moves at 4 m/s and the cheddar at 2 m/s, which has more kinetic energy?

• It depends on their masses

• Both have the same kinetic energy

• The Swiss

• The cheddar

What is the equation for kinetic energy?

• m^2v

• 1/2 mv

• mv^2

• 1/2 mv^2
