Front

What is a force?

Back

A force is a push or pull acting upon an object as a result of its interaction with another object.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How do you calculate net force when two forces act in opposite directions?

Back

Net force is calculated by subtracting the smaller force from the larger force.

Front

If a 80 N force and a 35 N force act in opposite directions, what is the net force?

Back

45 N in the direction of the larger force.

Front

What is the net force when a 10 N force and a 30 N force act in opposite directions?

Back

20 N in the direction of the larger force.

Front

What does it mean when forces are balanced?

Back

Balanced forces mean that the net force acting on an object is zero, resulting in no change in motion.

Front

What does it mean when forces are unbalanced?

Back

Unbalanced forces result in a net force that causes an object to accelerate in the direction of the greater force.

Front

What is the relationship between mass and force according to Newton's second law?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What is the formula for calculating net force?

Back

Net force (F_net) = F1 + F2 + ... + Fn, where forces in the same direction are added and forces in opposite directions are subtracted.

Front

What is an example of a situation with balanced forces?

Back

A book resting on a table experiences balanced forces: the weight of the book downward is balanced by the normal force of the table upward.
