Review Semester Exam CIA 3

Front

What is Net Force?

Back

Net Force is the overall force acting on an object when all the individual forces acting on it are combined. It determines the object's acceleration.

Front

What is the formula to calculate Net Force?

Back

Net Force (F) = Mass (m) x Acceleration (a)

Front

What drives the movement of tectonic plates?

Back

Convection currents in the asthenosphere drive the movement of tectonic plates.

Front

What evidence supports the theory of continental drift?

Back

The shape of the landmasses seems to fit together, suggesting they were once joined.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

How does mass affect acceleration?

Back

According to Newton's second law, an object with greater mass will have less acceleration when the same force is applied compared to an object with less mass.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration (F = m x a).

Front

What happens to an object at rest when a net force is applied?

Back

An object at rest will accelerate in the direction of the net force applied to it.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.
