True or False: Statics deals with bodies in motion.

False. Statics studies bodies at rest or in equilibrium.

Which of the following best describes the second law of Newton? A) F = ma B) F = mg C) F = mv D) F = m/a

A) F = ma

Riddle: I’m the measure of how hard a force pushes or pulls, often causing objects to move. What am I?

Force

What is the standard unit of force in the SI system?

Newton (N)

Fill in the blank: The gravitational constant G has a value of ______ in SI units.

6.673×10⁻¹¹ m³kg⁻¹s⁻²

True or False: The weight of an object is independent of its location on Earth.

False. The weight depends on the gravitational force acting on the mass, which varies with elevation.
