Physics Quiz: Magnetic and Gravitational Forces

Depends on distance and charge of the source.

Positive and negative attract, like charges repel (positive-positive, negative-negative).

A metal exposed to an electric field can temporarily become electromagnetic and attract magnetic objects.

Increase the battery charge to strengthen the electromagnet.

Range of electromagnetic radiation, includes visible light.

Mass is the amount of matter, while weight is the force of gravity on that matter.

The strength of gravity depends on the mass of objects and the distance between them.

Weight = mass × gravity. On Earth, the gravity constant is used in the calculation, while on the Moon the gravity is different.

Gravity isn't limited to Earth; it's a warp in spacetime that attracts objects.

In orbit, objects appear weightless due to free fall; they experience microgravity.

The strength of a magnetic field is affected by the distance from the source and the strength of the magnet itself.

Magnetic field lines connect like poles of a magnet, indicating that these poles are attracted to each other.

Magnetic field lines repel when magnets have opposite poles facing each other.

Earth's magnetic field is made by the molten metal movement in Earth's core and safeguards Earth from harmful solar radiation.

Both magnetic and gravitational fields are non-contact forces. However, gravity affects all masses, while magnetism only works on magnetic objects. Magnetic attractions and repulsions exist, but gravity always attracts.
