Balanced & Unbalanced Forces

Front

What is the force that pulls objects toward the Earth?

Back

Gravity is the force that pulls objects toward the Earth.

Front

What are forces that are equal in size and opposite in direction called?

Back

Balanced forces are equal in size and opposite in direction.

Front

What happens when the net force acting on an object is not zero?

Back

When the net force is not zero, the forces are unbalanced, causing the object to accelerate.

Front

What is the term for the push or pull on an object?

Back

A force is a push or pull on an object.

Front

What do we call the change in position of an object?

Back

Motion is the change in position of an object.

Front

What is the relationship between force, mass, and acceleration?

Back

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

Front

What is the direction of a force?

Back

The direction of a force is the line along which the force acts.

Front

What is an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is when one person pulls harder than another in a tug of war.

Front

What is the effect of balanced forces on an object's motion?

Back

Balanced forces do not change an object's motion; the object remains at rest or continues to move at a constant speed.

Front

What is the term for the total force acting on an object?

Back

The net force is the total force acting on an object.
