Balanced and Unbalanced forces

According to __________________________, a body at rest or in motion will remain in the unchanged position unless an external force is applied to it.

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Galileo's Law of Falling Bodies

A force where two forces of equal size, act on a body, in opposing directions is known as a _______________________.

• gravity

• friction

• balanced force

• unbalanced force

A force where two forces acting in opposing directions on a body, are not equal in magnitude and in size, is known as an __________________.

In an unbalanced force, a body changes its position i.e. we can observe a moving object ________________, either_______________________the speed or______________________ the speed and a body at rest starts to move and vice versa.

• stay at rest, increasing, decreasing

• change direction, increasing, decreasing

• stay at a constant speed, increasing, or decreasing

• stay at a constant speed, increasing, or cancelling

An example of a balanced force is...

• kicking a football so it moves from one place to another

• climate change

• A game of tug of war with equally matched opponents is an example of balanced force.

• meteor showers
