Centripetal Motion and Forces

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 does mass affect gravitational force?

Back

Gravitational force is directly proportional to the mass of the objects involved.

Front

What is the direction of the net force in uniform circular motion?

Back

The net force is directed toward the center of the circular path.

Front

What angle maximizes the range of a projectile in the absence of air resistance?

Back

45° is the angle that maximizes the range of a projectile.

Front

What happens to the vertical velocity of a projectile at its highest point?

Back

The vertical velocity is zero at the highest point of the projectile's path.

Front

What is the relationship between speed and acceleration in uniform circular motion?

Back

In uniform circular motion, the speed is constant, but the object is still accelerating due to the change in direction.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) is given by the formula a_c = v²/r, where v is the speed and r is the radius of the circular path.

Front

What is the effect of increasing the radius on centripetal force?

Back

Increasing the radius decreases the centripetal force required for an object to maintain circular motion at a constant speed.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
