Force & Net Force

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to start moving, stop moving, or change direction.

Front

What happens when the net force is 0N?

Back

When the net force is 0N, the object remains at rest or continues to move at a constant speed in a straight line.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass and speed of the object.

Front

How does direction affect force?

Back

Changing the direction of an object while maintaining its speed involves unbalanced forces, which can change the object's motion.

Front

What is the formula for calculating net force?

Back

Net force = Force applied - Force opposing.

Front

What is an example of an unbalanced force in sports?

Back

A soccer player kicking a ball is an example of an unbalanced force, as the kick changes the ball's motion.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass, pulling them towards each other.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes motion between two surfaces in contact, affecting how objects move.
