Test: Balanced and unbalanced forces - Year 8 MCQ

100g = 0.1kg, 0.1kg weighs 0.1 x 25 = 2.5N.
The weight of an object depends on the force of gravity that is acting on it.
The Moon has a gravity of about one sixth of that of the Earth, so 1kg would weigh a lot less than on the Earth, whilst on the planet Jupiter, it would weigh a lot more as the force of gravity there is larger

When two forces of equal magnitude act in opposite directions on an object, they cancel each other out. This results in a net force of zero, meaning the forces are balanced.

If an object is accelerating, it means there is a net force acting on it in the direction of its acceleration. Therefore, the forces acting on the object are unbalanced.

When forces acting on an object are balanced, the object experiences no net force. According to Newton's First Law of Motion, the object will continue in its current state of motion, which could be at rest or moving with a constant velocity.
