Newton's 2nd law flashcard

Front

What does Newton's 2nd Law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) = Force (F) / Mass (m).

Front

If a lawnmower and a car are pushed with the same force, which will accelerate more?

Back

The lawnmower will accelerate more because it has less mass.

Front

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

Back

The acceleration decreases.

Front

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

Back

Increasing the force increases the acceleration.

Front

What is centripetal force?

Back

Centripetal force is the force that acts on an object moving in a circular path, directed toward the center of the circle.

Front

If a car has a mass of 2500 kg and a force of 5000 N is applied, what is its acceleration?

Back

The acceleration is 2 m/s².

Front

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

Back

Force equals mass times acceleration (F = ma).

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What happens to the acceleration of an object if the net force acting on it is zero?

Back

If the net force is zero, the acceleration is also zero; the object remains at rest or continues to move at a constant velocity.
