IPC - Final Exam Review Fall

Front

What is the gravitational force exerted on an object?

Back

Weight

Front

What law states that when one object exerts a force on a second object, the second one exerts a force on the first that is equal in strength but opposite in direction?

Back

Newton's 3rd Law

Front

What is the formula for calculating acceleration?

Back

a = (v_f – v_o)/t

Front

According to Newton’s second law of motion, what is the relationship between force, mass, and acceleration?

Back

F = m • a

Front

What do we call the motion of an object falling under the influence of gravity alone, with no air resistance?

Back

Free fall

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the SI unit of force?

Back

Newton (N)

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the gravitational force acting on that mass.

Front

What is the formula for calculating net force?

Back

Net force = mass × acceleration (F = m • a)

Front

What does it mean for an object to be in equilibrium?

Back

The net force acting on the object is zero, resulting in no acceleration.
