Understanding Hooke's Law Concepts

The video explains Hooke's Law, focusing on the equation F = -KX and the significance of the negative sign. It clarifies that the negative sign indicates the direction of the force exerted by the spring, which is opposite to the displacement direction. The video covers scenarios of both positive and negative displacements, illustrating how the spring force acts in each case. The negative sign ensures the correct direction of force, aligning with the physical behavior of springs.

What is the primary purpose of the negative sign in Hooke's Law?

• To represent the spring constant

• To ensure the force direction is opposite to displacement

• To show the direction of displacement

• To indicate the magnitude of force

When a block is displaced to the right of the equilibrium point, what is the direction of the force exerted by the spring?

• Upwards

• To the right

• To the left

• Downwards

In Hooke's Law, what does a positive displacement indicate?

• The block is to the right of the equilibrium point

• The block is not moving

• The block is to the left of the equilibrium point

• The block is at the equilibrium point

Why is the spring constant considered a positive quantity?

• It represents the stiffness of the spring

• It indicates the direction of force

• It shows the displacement of the block

• It is a measure of the spring's length

What is the role of the spring constant in Hooke's Law?

• To quantify the stiffness of the spring

• To measure the displacement

• To indicate the equilibrium point

• To determine the direction of force

What does the negative sign in the equation F = -KX ensure when the block is on the right side?

• The force is positive

• The force is negative

• The displacement is zero

• The spring constant is negative

What happens to the force when the block is on the left side of the equilibrium point?

• The force is opposite to the displacement

• The force is in the same direction as displacement

• The force becomes zero

• The force increases indefinitely

How does the negative sign in Hooke's Law help when the block is on the left side of the equilibrium point?

• It makes the force positive

• It makes the displacement positive

• It reverses the direction of displacement

• It cancels out the spring constant

What is the effect of the negative sign on the force when the block is on the left side of the equilibrium point?

• It makes the force zero

• It reverses the force direction

• It doubles the force

• It has no effect

Why is it important to understand the negative sign in Hooke's Law?

• To measure the displacement

• To calculate the spring constant

• To predict the direction of force

• To find the equilibrium point
