FLASHCARD QUESTION

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object in such a way that they cancel each other out, resulting in no change in motion.

FLASHCARD QUESTION

Front

What is a Newton?

Back

A Newton is the SI unit of force. It is defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared.

3.

What does Newton's 2nd law state?

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 (F=ma).

FLASHCARD QUESTION

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of movement.

5.

FLASHCARD QUESTION

Front

What does unbalanced forces mean?

Back

Unbalanced forces occur when two or more forces acting on an object do not cancel each other out, resulting in a change in motion.

FLASHCARD QUESTION

Front

What is the relationship between force and acceleration?

Back

The relationship is described by Newton's 2nd law: greater force results in greater acceleration, while greater mass results in less acceleration.

7.

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.
