Balanced and Unbalanced Forces Assessment

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction. They do not cause a change in the motion of an object.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite. They cause an object to start moving, stop moving, or change direction.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will move in the direction of the greater force.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

If a toy car is moving at a constant speed, what type of forces are acting on it?

Back

The forces acting on the toy car are balanced forces.

Front

Give an example of unbalanced forces in everyday life.

Back

An example of unbalanced forces is when a person pushes a shopping cart, causing it to move.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It can slow down or stop moving objects.

Front

How does friction affect motion?

Back

Friction can cause an object to slow down or stop moving, making it an unbalanced force.

Front

What is an example of balanced forces in nature?

Back

An example of balanced forces in nature is a book resting on a table; the weight of the book is balanced by the support force of the table.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the Earth, creating a force that can be balanced or unbalanced depending on other forces acting on the object.
