FLASHCARD QUESTION

Front

What is Newton's 2nd Law of Motion?

Back

The 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 it mean when we say 'a larger force will be required to accelerate a roller coaster with more people'?

Back

It means that as the mass of the roller coaster increases (more people), a greater force is needed to achieve the same acceleration.

3.

FLASHCARD QUESTION

Front

What is inertia according to Newton's 1st Law of Motion?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

FLASHCARD QUESTION

Front

What is friction?

Back

Friction is a force that opposes the direction of motion of an object as it slides over a surface.

5.

FLASHCARD QUESTION

Front

What does Newton's 1st Law of Motion state?

Back

An object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by a net external force.

FLASHCARD QUESTION

Front

How does increasing the force applied to an object affect its acceleration?

Back

According to Newton's 2nd Law, increasing the force applied to an object results in greater acceleration.

7.

FLASHCARD QUESTION

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

The acceleration of an object is inversely proportional to its mass; as mass increases, acceleration decreases if the same force is applied.
