12/6 Friday's Test

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is the function of the immune system?

Back

The immune system fights germs (pathogens) and disease in the body.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, resulting in a change in motion of an object.

Front

How do you calculate net force?

Back

To calculate net force, add all the forces acting on an object, taking into account their direction.

Front

What happens when the net force is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant speed.

Front

What is an example of balanced forces?

Back

An example of balanced forces is a book resting on a table, where the force of gravity is balanced by the normal force of the table.

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is pushing a box across the floor, where the applied force is greater than the frictional force.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What does it mean if an object is in motion?

Back

If an object is in motion, it means that its position is changing relative to a reference point.
