The non-contact forces portfolio includes Gravitational force, Magnetic force and Electrostatic force.
<h3>What is non contact force?</h3>
Non contact forces are those forces which are applied on any object without any physical interference or contact.
Some non-contact forces are:
- Gravitational force: It acts between two objects and depends on the masses of the object and distance between that objects.
- Magnetic force: It acts due to the motion of the charged particles.
- Electrostatic force: It is a type of induced force which is generated due to rubbing of two objects but when it is generated it remains even after removing the contact of previous objects.
Hence Gravitational force, Magnetic force and Electrostatic force are the non-contact forces.

Answer:
Si.
Explicación:
Si un oficial de policía está controlando la velocidad en la carretera y dispara al vehículo con una pistola de radar. El policía mide la velocidad media del coche con esta pistola de radar. Una pistola de radar es un dispositivo que se utiliza para medir la velocidad de los objetos en movimiento que fue inventado por Bryce K. Brown en el año de 1954. La pistola de radar se utiliza con fines policiales para calcular la velocidad de los vehículos en movimiento.
