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 the formula for calculating centripetal force?

Back

Centripetal force (Fc) = (mass (m) * velocity (v)^2) / radius (r).

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

How do you calculate potential energy (PE)?

Back

Potential energy (PE) = mass (m) * gravitational acceleration (g) * height (h).

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in its energy. Work = Force * Distance.

Front

What is the work-energy principle?

Back

The work-energy principle states that the work done on an object is equal to the change in its kinetic energy.

Front

What is the formula for calculating kinetic energy (KE)?

Back

Kinetic energy (KE) = 0.5 * mass (m) * velocity (v)^2.

Front

What does a force vs. position graph represent?

Back

A force vs. position graph shows the relationship between the force applied to an object and its position, allowing calculation of work done.

Front

What is the significance of the area under a force vs. position graph?

Back

The area under the curve represents the work done on the object as it moves from one position to another.

Front

What is frictional force?

Back

Frictional force is the force that opposes the motion of an object in contact with a surface.
