Circular Motion and Gravity

Front

What is the formula for the circumference of a circle?

Back

C = 2πr, where r is the radius.

Front

What is the definition of circular motion?

Back

Circular motion is the motion of an object in a circular path.

Front

What is the relationship between speed and frequency in circular motion?

Back

Speed = Circumference × Frequency.

Front

What is inertia?

Back

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

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero.

Front

What is the direction of the velocity vector in circular motion?

Back

The velocity vector is always tangent to the circle.

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

What is gravitational force?

Back

Gravitational force is the attractive force between two masses.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with the mass of the objects involved.

Front

What is the formula for gravitational force?

Back

F = G(m1*m2)/r^2, where G is the gravitational constant.
