Answer explanation

pęd (w fizyce)

A value that never changes is:

• context

• compass

• content

• constant

A repeated movement in a substance or field of energy is:

• vibration

• equilibrium [równowaga (fizyczna)]

• conservation [zachowanie np. energii]

• law

A force of attraction or repulsion [prawo przyciągania i odpychania] is called:

• calculus

• magnetism

• momentum [pęd w fizyce]

• motion

A force that attracts bodies with mass towards each other is:

• conservation

• gravity

• wave

• momentum

What is electromagnetic force?

• The force due to gravity between two masses.

• The force that acts between charged particles, either attracting or repelling them.

• The force that binds protons and neutrons in an atom.

• The force that increases with the distance between two charges.

Which statement defines gravity?

• A force that is strongest at short distances.

• The force that only affects electrically charged particles.

• The force of attraction between any two masses.

• A force that causes electrical currents.

What is a gravitational field [pole grawitacyjne] ?

• A region around a charged object where electromagnetic forces act.

• A region around a mass where another mass experiences a force of attraction [siła przyciągania].

• The space around a magnet where magnetic forces occur.

• An area where gravitational force is zero.
