FLASHCARD QUESTION

Front

What is net force?

Back

The net force is the vector sum of all the forces acting on an object. If the forces are balanced, the net force is 0 N.

FLASHCARD QUESTION

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.

FLASHCARD QUESTION

Front

What is gravitational field strength?

Back

Gravitational field strength is the force of gravity acting on a unit mass at a specific location, measured in N/kg.

4.

FLASHCARD QUESTION

Front

How do you calculate centripetal acceleration?

Back

Centripetal acceleration (a_c) can be calculated using the formula: a_c = v^2 / r, where v is the velocity and r is the radius of the circular path.

FLASHCARD QUESTION

Front

What is the formula for gravitational force?

Back

The formula for gravitational force (F) is F = m * g, where m is mass and g is the gravitational field strength.

6.

FLASHCARD QUESTION

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as the product of mass and gravitational field strength (W = m * g).

7.

FLASHCARD QUESTION

Front

What is the significance of a 0 N net force?

Back

A net force of 0 N indicates that an object is in equilibrium, meaning it is either at rest or moving at a constant velocity.
