Mechanical Concepts Practice

What is the formula to calculate force?

• Force = Mass / Acceleration

• Force = Mass x Acceleration (F = ma)

• Force = Mass - Acceleration

• Force = Mass + Acceleration

Which of the following has direction and magnitude?

• velocity

• force

• momentum

• acceleration

What is the unit for force?

• Newton

• Second

• Kilogram

• Meter

What is the formula to calculate work?

• work = force + distance

• work = force ÷ distance

• work = force × distance

• work = force - distance

Which type of energy is associated with an object's position?

• kinetic energy

• nuclear energy

• potential energy

• thermal energy

What is the direction of centrifugal force?

• The direction of centrifugal force is perpendicular to the plane of rotation.

• The direction of centrifugal force is towards the center of rotation.

• The direction of centrifugal force is away from the center of rotation.

• The direction of centrifugal force is dependent on the mass of the object.
