Forces and Motion Concepts

What is the definition of force?

• A measure of mass

• A push or a pull

• A form of matter

• A type of energy

What happens to a book resting on a table when the forces are balanced?

• It starts to move

• It stays at rest

• It accelerates

• It changes direction

Which force acts upward on a pen hanging by a string?

• Gravitational force

• Tension force

• Frictional force

• Magnetic force

What occurs when the string holding a pen is cut?

• The pen moves sideways

• The pen moves upward

• The pen falls due to gravity

• The pen remains stationary

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

• The object remains at rest

• The object moves with constant velocity

• The object changes color

• The object accelerates

How do balanced forces affect a moving object?

• They cause the object to stop

• They increase the object's speed

• They change the object's direction

• They maintain the object's constant velocity

What can unbalanced forces change in a moving object?

• Only the object's shape

• The object's speed and direction

• The object's temperature

• Only the object's color

What is the net force when forces are balanced?

• Less than zero

• Undefined

• Greater than zero

• Equal to zero

What happens to an object when unbalanced forces act on it?

• It moves in the direction of the greater force

• It becomes lighter

• It remains stationary

• It changes color

What is the effect of balanced forces on a stationary object?

• The object heats up

• The object changes direction

• The object remains at rest

• The object accelerates
