In the equation P = ½kx², what does 'k' represent?

• Height of the object

• Mass of the object

• Spring constant

• Gravitational constant

According to Hooke's Law, the force exerted by a spring is:

• Directly proportional to the mass of the object

• Directly proportional to the stretch of the spring

• Inversely proportional to the stretch of the spring

• Inversely proportional to the spring constant

Which equation represents Hooke's Law?

• F = kx

• P = ½kx²

• PE = mgh

• K = ½mv²

How can the spring constant 'k' be determined experimentally?

• By measuring the mass of the spring

• By measuring the stretch of the spring at various forces and plotting the points

• By calculating the gravitational potential energy

• By using the equation K = ½mv²

What is the value of the gravitational constant 'g' used in the equation F = mg?

• 8.9 m/s²

• 9.8 m/s²

• 10.8 m/s²

• 7.8 m/s²
