Module 6 Quiz

What is the SI unit for weight?

• Kilogram (kg)

• Newton (N)

• Meter per second squared (m/s^2)

• Joule (J)

What is the SI unit for mass?

• Kilogram (kg)

• Newton (N)

• Meter per second squared (m/s^2)

• Joule (J)

What is the force by which a gravitational field attracts an object?

• Mass

• Weight

• Acceleration

• Velocity

What is the difference between weight and mass?

• Weight is measured in kilograms, while mass is measured in newtons.

• Mass is a vector quantity, while weight is a scalar quantity.

• Weight is constant, while mass depends on the strength of the gravitational field.

• Weight depends on the strength of the gravitational field, while mass is constant.

What is the equation for weight?

• W = m - g

• W = m * g

• W = m + g

• W = m/g

What is the strength of the gravitational field on Earth?

• Zero (no gravity)

• 3.34 N/kg

• 9.81 m/s^2 downwards

• 6.67 x 10^-11 N m^2/kg^2

What happens when the upward force due to drag is equal in magnitude to the downward force experienced in the Earth's gravitational field?

• The object will continue to accelerate until impact.

• The object will be in free fall.

• The object will experience a zero resultant force.

• The object will reach terminal velocity.

What is the concept of terminal velocity?

• The velocity at which an object is at rest.

• The velocity at which an object starts to accelerate.

• The maximum velocity an object can reach when falling.

• The velocity at which an object experiences free fall.

What is the force that opposes the downward motion of a falling object?

• Supportive force

• Centripetal force

• Horizontal force

• Drag

What happens when all of the forces acting on an object result in a zero resultant force?

• The object will decelerate.

• The object will accelerate.

• The forces are unbalanced.

• The forces are balanced.
