What is Hooke's Law?

Back

Hooke's Law states that the force exerted by a spring is directly proportional to the amount it is stretched or compressed, represented mathematically as F = kx, where F is the force, k is the spring constant, and x is the displacement from the equilibrium position.

Front

What is the spring constant (k)?

Back

The spring constant (k) is a measure of a spring's stiffness, defined as the force required to compress or extend the spring by a unit distance, measured in N/m.

Front

How do you calculate the force needed to compress a spring?

Back

The force needed to compress a spring can be calculated using Hooke's Law: F = kx, where F is the force, k is the spring constant, and x is the distance the spring is compressed.

Front

What type of energy is stored in a compressed or stretched spring?

Back

The energy stored in a compressed or stretched spring is called elastic potential energy.

Front

What is the formula for elastic potential energy (EPE)?

Back

The formula for elastic potential energy is EPE = 1/2 kx², where k is the spring constant and x is the displacement from the equilibrium position.

Front

What is simple harmonic motion (SHM)?

Back

Simple harmonic motion is a type of periodic motion where an object moves back and forth around an equilibrium position, with a restoring force proportional to the displacement from that position.

Front

What is the period of a mass-spring system?

Back

The period of a mass-spring system is the time taken to complete one full cycle of motion, calculated as T = 2π√(m/k), where m is the mass and k is the spring constant.

Front

What is the relationship between frequency and period?

Back

Frequency (f) is the reciprocal of the period (T), expressed as f = 1/T. It represents the number of cycles per second.

Front

What happens to the spring constant if a spring is stretched beyond its elastic limit?

Back

If a spring is stretched beyond its elastic limit, it may not return to its original shape, and the spring constant may change or the spring may become permanently deformed.

Front

How does mass affect the oscillation of a spring?

Back

Increasing the mass attached to a spring decreases the frequency of oscillation and increases the period, resulting in slower oscillations.
