Force & Net Force

Front

What is force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is net force?

Back

The total force acting on an object after all the individual forces are combined.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Forces that are not equal and can cause an object to accelerate or change direction.

Front

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

Back

The object remains at rest or continues to move at a constant speed in a straight line.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

How does changing direction affect net force?

Back

Changing direction while maintaining speed creates unbalanced forces, affecting the net force.

Front

What is the formula for calculating net force?

Back

Net Force = Force applied - Force of resistance.

Front

What is an example of balanced forces in everyday life?

Back

A book resting on a table, where the force of gravity is balanced by the normal force from the table.

Front

What is an example of unbalanced forces?

Back

A soccer ball being kicked, where the force of the kick is greater than the resistance from the ground.
