The gravitational attraction by the Sun.
centripetal force
centripetal force
-- If all the forces on a planet were balanced, then the planet would move in a straight line with constant speed, not in a curved path. So the forces on it must be unbalanced. -- That's easy to understand when you consider that there's only one force on the planet ... the force of gravity that attracts it toward the sun. That force is a centripetal one.
Centripetal force is a force that makes a body follow a curved path. An example of centripetal force is gravity making something in space orbit Earth. Mud flying in circles from a tire going down the road is centripetal force.
centripetal force.
Yes. According to Newton's Second Law, there has to be an unbalanced force - otherwise, the satellite won't accelerate (in this case, change direction).
Centripetal Force.That force is, of course, supplied by gravitional force.
The gravitational force between planets supplies the centripetal force that causes them to orbit each other.
Centripetal, I think. You're in eighth garde science, aren't you? Centripetal, I think. You're in eighth garde science, aren't you?
Centripetal force and Gravity
both are planets and are orbit with centripetal force. think about the atmospheres. They orbit around one another.
The forces of attraction between the sun and each planet are gravitational forces, and they're both centripetal forces.
