Balanced and Unbalanced Forces

What is the definition of balanced forces?

• Two forces acting in the same direction on an object, and equal in size.

• Two forces acting in opposite directions on an object, but not equal in size.

• One force acting on an object and causing it to move in a circular path.

• Two forces acting in opposite directions on an object, and equal in size.

Can you provide an example of balanced forces?

• A car accelerating uphill

• Two people pushing a box with the same amount of force in opposite directions.

• A rocket taking off into space

• A person lifting a heavy object

What is the definition of unbalanced forces?

• Unbalanced forces occur when two forces acting on an object are not equal in size and opposite in direction, causing a change in the object's motion.

• Unbalanced forces occur when two forces acting on an object are not equal in size and in the same direction, causing a change in the object's motion.

• Unbalanced forces occur when two forces acting on an object are equal in size and opposite in direction, causing a change in the object's motion.

• Unbalanced forces occur when two forces acting on an object are equal in size and opposite in direction, causing no change in the object's motion.

What are the effects of balanced forces?

• Decreased speed of the object

• No change in the object's motion

• Increased speed of the object

• Change in the object's direction

What are the effects of unbalanced forces?

How does gravity affect balanced forces?

• It causes the objects to move in the opposite direction

• It keeps the objects in equilibrium and prevents any movement.

• It increases the speed of the objects

• It has no effect on balanced forces

How does gravity affect unbalanced forces?

• It causes objects to move sideways.

• It causes objects to accelerate towards the center of the Earth.

• It has no effect on unbalanced forces.

• It causes objects to move away from the center of the Earth.
