Why is a frame of reference important when discussing forces and motion?

• It affects how we perceive and measure motion
• It allows us to calculate the distance an object travels
• It helps us understand the concept of acceleration
• It helps us measure the force applied to an object

What is a frame of reference in the context of motion and forces?

• A point of reference
• A set of coordinates
• A measurement tool
• A system of units

How does Newton's Second Law connect the concepts of force, mass, and acceleration?

• A larger mass will cause a larger acceleration.
• A larger force will cause a smaller acceleration.
• A larger force will cause a larger acceleration.
• A larger mass will cause a smaller acceleration.
