Conceptual Physics Sem 1 Final Exam Study Guide

Front

What can be inferred about the forces acting on an object moving at a constant velocity on a frictionless surface?

Back

The forces are balanced, resulting in no net force.

Front

According to Aristotle, how is the motion of an object described if it occurs without any external force?

Back

Motion that occurs without any external force.

Front

What does Newton's first law of motion state about an object at rest?

Back

An object at rest will remain at rest unless acted upon by a nonzero net force.

Front

What conclusion can be drawn about technological progress today compared to thousands of years ago?

Back

Progress is much quicker now than it was thousands of years ago.

Front

What happens to a spaceship's motion if no external forces act on it in space?

Back

It will continue moving at a constant velocity.

Front

Define net force in the context of motion.

Back

Net force is the vector sum of all forces acting on an object, determining its acceleration.

Front

What is inertia and how does it relate to Newton's first law?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is the basis for Newton's first law.

Front

Explain the concept of balanced forces.

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.
