Test: Forces and their effects - Year 7 MCQ

Mass remains constant regardless of the location or gravitational force acting on the object.

Jupiter has a higher gravitational acceleration (g) compared to Earth, so the weight of an object would be greater on Jupiter.

Terminal velocity is the maximum speed achieved by a falling object when the force of gravity is balanced by the drag force of the surrounding fluid (e.g., air).

Air resistance (drag force) acts opposite to the direction of motion of a falling object, increasing as speed increases until terminal velocity is reached.

Earth has a gravitational acceleration of approximately 9.81 m/s², which is higher compared to other planets listed here.

Terminal velocity occurs when the force of gravity pulling an object downward is balanced by the drag force (air resistance) pushing upward.

Isaac Newton's law of universal gravitation explains the gravitational attraction between objects based on their masses and distance between them.
