when any object moves in circular path a force must act towards the center of the circle.
i )what word is used to describe this force?
ii )as the moon orbits the earth what provides the force towards the center?
iii )an atom, name the particles which are moving in a circular path around the nucleus?
Answers
Explanation:
(i) centripetal force
A centripetal force is a net force that acts on an object to keep it moving along a circular path. ... Newton's 1ˢᵗ law tells us that an object will continue moving along a straight path unless acted on by an external force. The external force here is the centripetal force.
(ii)Earth's gravity
Gravitational attraction provides the centripetal force needed to keep planets in orbit around the Sun and all types of satellite in orbit around the Earth. The Earth's gravity keeps the Moon orbiting us. It keeps changing the direction of the Moon's velocity.
(iii) electrons
The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus. The electrons have a negative electrical charge.
hopefully it will work ☺️☺️
