FLASHCARD QUESTION
Front
Back
Newton's 2nd 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 is the formula to calculate net force?
Back
The formula to calculate net force is F_net = m * a, where F_net is the net force, m is the mass of the object, and a is the acceleration.

FLASHCARD QUESTION
Front
If a 25 kg bike accelerates at 10 m/s², what is the net force?
Back
250 N (calculated using F = ma: F = 25 kg * 10 m/s²).

FLASHCARD QUESTION
Front
What happens to an object at rest when unbalanced forces act on it?
Back
The object begins moving in the direction of the net force.
5.
FLASHCARD QUESTION
Front
If the net force acting on an object doubles along with the mass of the object, what happens to the acceleration?
Back
The acceleration stays the same.

FLASHCARD QUESTION
Front
What is inertia?
Back
Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

FLASHCARD QUESTION
Front
How does mass affect acceleration when a constant force is applied?
Back
As mass increases, acceleration decreases if the force remains constant, according to F = ma.
