Newton's Laws of Motion

Flashcards summarizing key concepts from Newton's Laws of Motion.

What does Newton's First Law state?

An object will remain at rest or at a constant speed unless acted upon by an external resultant force.

How is acceleration calculated according to Newton's Second Law?

Acceleration is calculated using the formula: Resultant Force = Mass x Acceleration.

What is Newton's Third Law?

If body A exerts a force onto body B, then body B will exert an equal and opposite force onto body A.

What is terminal speed in the context of skydiving?

Terminal speed is reached when the upward air resistance equals the downward weight of the skydiver, resulting in no further acceleration.

What changes about air resistance during a skydiver's fall?

Air resistance changes due to the change in speed of the skydiver.
