Force & Net Force

Front

What is the definition of force in physics?

Back

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

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion. Unbalanced forces cause a change in motion.

Front

What happens to an object at rest when balanced forces act on it?

Back

The object remains at rest.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

How can you determine the direction of net force?

Back

The direction of net force is the same as the direction of the greater force when forces are unbalanced.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = F1 + F2 + ... + Fn, where F1, F2, ..., Fn are the individual forces acting on the object.

Front

In a tug-of-war, what determines which team wins?

Back

The team that exerts the greater net force on the rope will win.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

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).
