Mid-term Exam Part 2

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 of an object.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. If the net force is 0N, the object is in equilibrium.

Front

How much Iron (Fe) was created?

Back

33.5 grams.

Front

What is the tilt of the Earth?

Back

The object remains at rest.

Front

What happens to an object in motion when balanced forces act on it?

Back

The object continues to move at a constant velocity.

Front

Define unbalanced forces.

Back

Unbalanced forces are forces that are not equal in size or opposite in direction, causing a change in the motion of an object.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate, decelerate, or change direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
