Force & Net Force

Front

What is a balanced force?

Back

A balanced force occurs when two or more forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

What happens to an object when it experiences an unbalanced force?

Back

The object will change its state of motion, either speeding up, slowing down, or changing direction.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their directions.

Front

If two forces of 5 N and 3 N act in the same direction, what is the net force?

Back

The net force is 8 N in the direction of the forces.

Front

If two forces of 10 N and 4 N act in opposite directions, what is the net force?

Back

The net force is 6 N in the direction of the larger force.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object; without force, an object at rest stays at rest, and an object in motion continues in motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is directly related to the mass of the object.
