Mechanics and Dynamics in Physics Quiz

Vector quantity implies direction as well as magnitude; acceleration has both.

Newton's second law states force equals mass times acceleration.

When displacement is perpendicular to the force, no work is done.

Torque is measured in Newton-meters.

Scalars have only magnitude; displacement is a scalar.

This equation represents the displacement of a particle undergoing simple harmonic motion.

The total momentum of a closed system remains constant over time.

It describes the force of attraction between two masses.

Static equilibrium is a type of equilibrium.

Friction dissipates mechanical energy and is non-conservative.

A projectile follows a parabolic trajectory in the absence of air resistance.

It states mechanical energy remains constant if only conservative forces are at work.

In uniform circular motion, velocity is constant, but direction changes.

Pressure is uniform in all directions in hydrostatic equilibrium.
