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 = ma.
2.
FLASHCARD QUESTION
Front
What does the formula F = ma represent?
Back
F = ma represents the relationship between force (F), mass (m), and acceleration (a). It shows that force equals mass times acceleration.

If a 20 kg bike accelerates at 10 m/s², what is the force applied?
Back
200 Newtons.
4.
FLASHCARD QUESTION
Front
How do you calculate acceleration using force and mass?
Back
Acceleration can be calculated using the formula a = F/m, where F is the force applied and m is the mass of the object.

What is the mass of a golf ball if a force of 15 N causes it to accelerate at 25 m/s²?
Back
0.6 kg.

FLASHCARD QUESTION
Front
Define Balanced Forces.
Back
Balanced forces are two forces acting in opposite directions on an object, and they are equal in size, resulting in no change in motion.
