Forces and Momentum Quiz

Gravity is one of the fundamental forces that governs interactions between objects with mass.

When a book rests on a table, the forces acting on it are balanced, resulting in no change in its motion.

The unit of momentum in the SI system is kilogram-meter per second (kg·m/s).

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction.

The Newton is the unit of force in the International System of Units (SI).

Momentum is calculated by multiplying an object's mass by its velocity.

In equilibrium, the net force acting on an object is zero, meaning it has no specific direction.

If the net force acting on an object is zero, its momentum remains constant.

Velocity, being a quantity with both magnitude and direction, is a vector quantity.

Friction is the force that opposes the relative motion or tendency of motion between two surfaces in contact.

The law of conservation of momentum states that in the absence of external forces, the total momentum of a system remains unchanged.

The SI unit of force is the Newton, named after Sir Isaac Newton.

According to Newton's second law, force is equal to the product of an object's mass and its acceleration.

In collisions between objects, momentum is conserved.

The force exerted by a fluid on an object moving through it is called drag force.
