Review Quiz (3rd Qtr)

Which of the following is an example of balanced forces?

• A car accelerating

• A book resting on a table

• A ball rolling downhill

• A person pushing a cart forward

What is the result of balanced forces acting on an object?

• The object accelerates

• The object changes direction.

• The object slows down.

• The object remains stationary or moves at constant velocity

Why does a stationary object remain at rest?

• Because balanced forces act on it.

• Because there are no forces acting on it

• Because friction stops it from moving

• Because gravity is stronger than all other forces

Which situation illustrates unbalanced forces?

• A kite stuck in a tree.

• A ball remaining in one spot on the ground.

• A chair resting on the floor

• A tug-of-war game where one team pulls the other forward

A car slows down as the driver applies the brakes. What type of forces are acting on it?

• Balanced

• Newton

• Unbalanced

• Weight

You push a box, but it doesn't move. What type of forces are acting on it?

• Balanced

• Newton

• Unbalanced

• Weight

Analyze the forces acting on a hanging lamp. Why does it stay in place?

• Because it is having balanced

• Because it is having newton

• Because it is having unbalanced

• Because it is having weight

What is a scalar quantity?

• A quantity with direction only

• A quantity with magnitude only

• A quantity that cannot be measured

• A quantity with both magnitude and direction

Which of the following is an example of a vector quantity?

• Distance

• Speed

• Temperature

• Velocity

How does a vector quantity differ from a scalar quantity?

• Scalars are always larger than vectors.

• Scalars have direction, but vectors do not.

• Scalars can only be positive, while vectors can be negative.

• Vectors have magnitude and direction, while scalars have only magnitude.
