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
How do you calculate mass using Newton's 2nd Law?
Back
Mass can be calculated using the formula m = F/a, where F is the net force applied to the object and a is the acceleration.
3.
FLASHCARD QUESTION
Front
If a force of 250 N results in an acceleration of 5 m/s², what is the mass of the object?
Back
The mass of the object is 50 kg, calculated using m = F/a = 250 N / 5 m/s².
4.
FLASHCARD QUESTION
Front
What happens to the acceleration of an object if the force applied to it increases?
Back
The acceleration of the object increases, as acceleration is directly proportional to the net force applied.
5.
FLASHCARD QUESTION
Front
If two objects have the same force applied but different masses, which will have a greater acceleration?
Back
The object with the smaller mass will have a greater acceleration, as acceleration is inversely proportional to mass.
6.
FLASHCARD QUESTION
Front
What is the relationship between mass and force required to change an object's motion?
Back
The larger the mass of an object, the more force is needed to change its motion.
7.
FLASHCARD QUESTION
Front
If the net force on an object doubles, what happens to its acceleration?
Back
The acceleration also doubles, as acceleration is directly proportional to net force.
