Net Forces Review

Front

What happens if the sum of the forces acting on an object is zero?

Back

The forces are balanced, and the object won't move.

Front

What is the force that resists motion when two surfaces rub together?

Back

Friction.

Front

If your dad pushes a couch with a force of 35 N to the right and you push with a force of 25 N to the right, what is the net force on the couch?

Back

60 N to the right.

Front

What is an example of an unbalanced force?

Back

An unbalanced force occurs when the total force acting on an object is not zero, causing it to accelerate.

Front

What is a force?

Back

A force is the PUSH or PULL on an object.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion, while unbalanced forces cause an object to accelerate.

Front

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

Back

Newton (N).

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What is an example of friction in everyday life?

Back

Walking on the ground, where the friction between your shoes and the surface prevents slipping.
