Terminal Velocity and Forces Quiz

What is terminal velocity?

• The speed at which an object starts moving

• The speed at which an object stops moving

• The maximum speed of an object when forces are balanced

• The speed at which gravity no longer affects an object

What is the acceleration of an object falling freely near the Earth's surface?

• 8.9 m/s²

• 10 m/s²

• 9.0 m/s²

• 9.8 m/s²

What happens to a skydiver's speed when the parachute opens?

• The skydiver slows down

• The skydiver stops immediately

• The skydiver speeds up

• The skydiver goes upwards

What is the resultant force on an object at terminal velocity?

• Equal to the gravitational force

• Equal to the weight of the object

• Zero

• Equal to the frictional force

Which force increases as a skydiver gains speed?

• Magnetic force

• Nuclear force

• Gravitational force

• Air resistance

What is the role of frictional forces in reaching terminal velocity?

• They eliminate air resistance

• They increase the object's speed

• They balance the gravitational force

• They decrease the object's weight

What is the initial force acting on a skydiver when they leave the aircraft?

• Frictional force

• Air resistance

• Gravitational force

• Magnetic force

What happens to the resultant force as an object approaches terminal velocity?

• It reverses direction

• It remains constant

• It increases

• It becomes zero

What is the effect of opening a parachute on air resistance?

• It eliminates air resistance

• It decreases air resistance

• It has no effect on air resistance

• It increases air resistance

What is the relationship between force and acceleration?

• Force is inversely proportional to acceleration

• Force is directly proportional to acceleration

• Force is unrelated to acceleration

• Force is equal to acceleration
