FLASHCARD QUESTION

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be expressed with the formula: F = ma (Force = mass x acceleration).

2.

FLASHCARD QUESTION

Front

What does the formula F = ma represent?

Back

The formula F = ma represents Newton's Second Law of Motion, where F is the net force applied to an object, m is the mass of the object, and a is the acceleration produced.

FLASHCARD QUESTION

Front

What happens to an object's acceleration if the mass increases while the force remains constant?

Back

If the mass of an object increases while the force remains constant, the acceleration of the object decreases.

4.

FLASHCARD QUESTION

Front

What is meant by unbalanced forces?

Back

Unbalanced forces occur when the total force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

5.

FLASHCARD QUESTION

Front

If two objects are pushed with the same force, how does their mass affect their acceleration?

Back

The object with less mass will have greater acceleration compared to the object with more mass when both are pushed with the same force.

6.

FLASHCARD QUESTION

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is that force equals mass times acceleration (F = ma). This means that for a given mass, increasing the force will increase the acceleration.

7.

FLASHCARD QUESTION

Front

What happens to an object at rest when unbalanced forces act on it?

Back

When unbalanced forces act on an object at rest, it begins moving in the direction of the net force.
