Which force is primarily responsible for propelling a machine?

• Frictional force

• Propulsive force

• Magnetic force

• Gravitational force

How does propulsion affect a machine's efficiency?

• It decreases efficiency by increasing energy consumption

• It has no effect on efficiency

• It makes the machine slower

• It increases efficiency by optimizing energy use
