Forces and Net Force Quiz

What is a balanced force?

• Two equal forces acting in opposite directions

• Two unequal forces acting in opposite directions

• Two equal forces acting in the same direction

• A single force acting on an object

Give an example of balanced forces in everyday life.

• Pushing a stationary box with equal force from both sides

• Pushing a box with more force from one side than the other

• Two people pushing a box in opposite directions with different amounts of force

• Pulling a heavy object from one side only

Define unbalanced force.

• A force that causes a change in the motion of an object.

• A force that causes an object to remain at rest

• A force that keeps an object in motion

• A force that has no effect on the motion of an object

Explain how unbalanced forces can cause an object to move.

• Unbalanced forces cause an object to move by changing its motion in the opposite direction of the greater force

• Unbalanced forces cause an object to move by reducing its speed

• Unbalanced forces cause an object to move by keeping it stationary

• Unbalanced forces cause an object to move by changing its motion in the direction of the greater force.

What is the net force when two forces of 5N and 3N act in the same direction?

• 2N

• 10N

• 15N

• 8N

If two forces of 8N and 6N act in opposite directions, what is the net force?

• 10N

• 4N

• 2N

• 14N

How do you calculate the net force when forces are acting in the same direction?

• Divide the individual forces

• Add the individual forces together

• Multiply the individual forces

• Subtract the individual forces

How do you calculate the net force when forces are acting in opposite directions?

• Add the forces together

• Subtract the smaller force from the larger force.

• Divide the forces by 2

• Ignore the forces and calculate the net force based on the object's mass

Explain the concept of equilibrium in relation to balanced forces.

• The object is in a state of equilibrium when the forces acting on it are unbalanced.

• Equilibrium is only achieved when the object is in motion.

• The object is in a state of equilibrium when the forces acting on it are balanced.

• Equilibrium occurs when the forces are constantly changing.

What happens to an object when the net force acting on it is zero?

• It remains at rest or continues to move at a constant velocity

• It explodes

• It disappears into thin air

• It accelerates in the opposite direction
