Centripetal Force

Front

What is centripetal force?

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed towards the center of the circle, causing the object to accelerate towards that center.

Front

How is centripetal acceleration calculated?

Back

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

Front

What is the relationship between mass, velocity, and centripetal force?

Back

The centripetal force (F_c) can be calculated using the formula: F_c = (m * v^2) / r, where m is the mass of the object, v is the velocity, and r is the radius of the circular path.

Front

What happens to the centripetal force if the speed of the object increases?

Back

If the speed of the object increases while moving in a circular path, the centripetal force must also increase to maintain the circular motion.

Front

What is the formula for calculating the force of friction?

Back

The force of friction (F_f) can be calculated using the formula: F_f = μ * N, where μ is the coefficient of friction and N is the normal force.

Front

What is equilibrium in the context of forces?

Back

Equilibrium occurs when the net force acting on an object is zero, resulting in no acceleration. This can happen when all forces acting on the object balance each other.

Front

How do you determine the net force acting on an object?

Back

The net force acting on an object is determined by vectorially adding all the individual forces acting on it, taking into account their magnitudes and directions.

Front

What is the significance of the angle in force applications?

Back

The angle at which a force is applied affects the components of that force. The horizontal and vertical components can be calculated using trigonometric functions (cosine and sine) based on the angle.

Front

What is the role of mass in determining acceleration?

Back

According to Newton's second law, the acceleration of an object is inversely proportional to its mass when a constant force is applied. This means that greater mass results in less acceleration.

What is the effect of a frictionless surface on motion?

Back

On a frictionless surface, an object can move without any resistance, allowing it to maintain its velocity indefinitely unless acted upon by an external force.
