Balanced & Unbalanced Forces

Example of balanced forces in everyday life?

• A book resting on a table is an example of balanced forces; the weight of the book is balanced by the upward force of the table.

• A car accelerating on a straight road is an example of balanced forces.

• A person pushing a wall with all their strength is an example of balanced forces.

• A balloon rising in the air is an example of balanced forces.

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

• An object will remain at rest.

• An object will accelerate, decelerate, or change direction.

• An object will always move in a straight line.

• An object will stop moving completely.

What is a net force?

• The total force acting on an object when all forces are combined.

• The force that opposes motion.

• The force applied to an object to start its movement.

• The force that acts on an object due to gravity.

Can balanced forces change the shape of an object?

• Yes, balanced forces can change the shape of an object, like squeezing a sponge, but they do not change its motion.

• No, balanced forces cannot change the shape of an object at all.

• Yes, balanced forces can change the motion of an object significantly.

• Yes, balanced forces can only change the color of an object.

What is inertia?

• The force that causes an object to move in a circular path.

• The tendency of an object to resist changes in its state of motion.

• The speed at which an object travels in a straight line.

• The gravitational pull that affects an object's weight.

What are balanced forces?

• Forces that are unequal in size and direction, causing motion.

• Forces that are equal in size and opposite in direction, resulting in no change in motion.

• Forces that act on an object in the same direction, increasing its speed.

• Forces that are always present in a moving object, regardless of direction.

How does mass affect the motion of an object?

• The greater the mass of an object, the more force is needed to change its motion, making it harder to accelerate with unbalanced forces.

• Mass has no effect on the motion of an object; only force matters.

• Lighter objects always move faster than heavier objects regardless of the force applied.

• Mass affects motion only when the object is in a vacuum.

How do balanced forces affect a moving car?

• They cause the car to accelerate.

• If a car is moving at a constant speed in a straight line, the forces acting on it are balanced.

• They make the car change direction.

• They increase the car's speed.

What are unbalanced forces?

• Forces that are equal in size and opposite in direction.

• Forces that cause no change in the motion of an object.

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

• Forces that act on an object but do not affect its motion.

Example of unbalanced forces in everyday life?

• A marble rolling down a ramp is an example of unbalanced forces; gravity pulls it down while no opposing force is equal.

• A book resting on a table is an example of unbalanced forces; the table pushes up with equal force.

• A car parked on a flat road is an example of unbalanced forces; the engine is off and no forces are acting on it.

• A person pushing a stationary wall is an example of unbalanced forces; the wall does not move.
