Uniform Circular Motion

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 velocity and r is the radius of the circular path.

Front

What is the definition of uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed along a circular path.

Front

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

Back

In uniform circular motion, the velocity is tangent to the circular path, while the acceleration (centripetal acceleration) points towards the center of the circle.

Front

What are vector quantities?

Back

Vector quantities are physical quantities that have both magnitude and direction, such as velocity, acceleration, and force.

Front

What is the direction of centripetal acceleration?

Back

Centripetal acceleration always points towards the center of the circle.

Front

How does the mass of an object affect its centripetal acceleration?

Back

The mass of an object does not affect its centripetal acceleration; it is determined by the velocity and radius of the circular path.

Front

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

Back

If the speed of the object increases, the centripetal acceleration increases, as it is proportional to the square of the velocity (a_c = v²/r).

Front

What is the significance of the radius in uniform circular motion?

Back

The radius of the circular path affects the centripetal acceleration; a larger radius results in lower centripetal acceleration for the same speed.

Front

In which direction does the acceleration point when an object is moving clockwise in a circle?

Back

When an object is moving clockwise in a circle, the acceleration points towards the center of the circle.

Front

What is the relationship between the direction of velocity and acceleration in circular motion?

Back

In circular motion, the velocity is tangent to the path, while the acceleration is directed towards the center of the circle.
