Forces and Energy Exam Practice

What are the four main forces that affect flight?

• Gravity, wind, temperature, and pressure
• Thrust, drag, lift, and weight
• Speed, direction, altitude, and momentum
• Friction, acceleration, rotation, and balance

Which force pushes an object forward during flight?

• Drag
• Weight
• Lift
