Centripetal Intro

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.

Front

How is centripetal acceleration calculated?

Back

Centripetal acceleration (a_c) is calculated using the formula: a_c = v^2 / r, where v is the tangential 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 * a_c, where m is the mass of the object and a_c is the centripetal acceleration.

Front

What is the formula for calculating the distance fallen by an object under gravity?

Back

The distance (d) fallen by an object under gravity can be calculated using the formula: d = 0.5 * g * t^2, where g is the acceleration due to gravity (approximately 9.81 m/s²) and t is the time in seconds.

Front

What is the significance of the radius in circular motion?

Back

The radius of the circular path affects both the centripetal acceleration and the centripetal force required to maintain circular motion; a larger radius results in lower centripetal acceleration for the same speed.

Front

How does speed affect centripetal acceleration?

Back

Centripetal acceleration increases with the square of the speed; if the speed doubles, the centripetal acceleration increases by a factor of four.

Front

What is the direction of centripetal acceleration?

Back

Centripetal acceleration always points towards the center of the circular path, perpendicular to the object's velocity.

Front

What is the difference between linear speed and angular speed?

Back

Linear speed refers to the distance traveled per unit of time, while angular speed refers to the angle through which an object moves per unit of time.

Front

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

Back

The net force acting on an object in circular motion is equal to the centripetal force required to keep the object moving in a circle, which can be calculated using F_c = m * a_c.

Front

What is the effect of mass on centripetal force?

Back

The centripetal force required to maintain circular motion increases with the mass of the object; more massive objects require greater force to maintain the same circular path.
