Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

How do you calculate force?

Back

Force can be calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

What is centripetal force?

Back

Centripetal force is the force that keeps an object moving in a circular path, directed towards the center of the circle.

Front

What is the formula for centripetal force?

Back

The formula for centripetal force is F_c = \frac{mv^2}{r}, where m is mass, v is velocity, and r is the radius of the circular path.

Front

How does increasing velocity affect centripetal force?

Back

Increasing the velocity of an object in circular motion increases the centripetal force required to keep it moving in that path.

Front

What happens to centripetal force if the radius is increased?

Back

If the radius is increased while keeping mass and velocity constant, the centripetal force decreases.

Front

How do you convert minutes to hours?

Back

To convert from minutes to hours, divide the number of minutes by 60.

Front

What is the direction of centripetal force in circular motion?

Back

The direction of centripetal force is always directed toward the center of the circular path.

Front

What is the relationship between mass and force in Newton's Second Law?

Back

In Newton's Second Law, force is directly proportional to mass; as mass increases, force must also increase to maintain the same acceleration.

Front

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

Back

The unit of force in the SI system is the Newton (N).
