What is Newton's second law of motion?
Back
Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F = M x A.
2.
FLASHCARD QUESTION
Front
What is the formula to calculate force?
Back
F = M x A, where F is force, M is mass, and A is acceleration.

FLASHCARD QUESTION
Front
What is acceleration?
Back
Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

FLASHCARD QUESTION
Front
If a force of 10 N is applied to a mass of 2 kg, what is the acceleration?
Back
A = F / M = 10 N / 2 kg = 5 m/s².
