Conceptual Physics midterm review 2025

Front

What is the net force when there are equal forces acting in opposite directions?

Back

0N

Front

What does the slope on a velocity-time graph represent?

Back

Acceleration

Front

Which of Newton's laws states that for every action, there is an equal and opposite reaction?

Back

Newton's 3rd law

Front

How do you calculate the speed of an object?

Back

Speed = Distance / Time

Front

What is the velocity of an object?

Back

Velocity is speed with a direction.

Front

What is the formula for calculating net force?

Back

Net Force = Sum of all forces acting on an object.

Front

What is the difference between speed and velocity?

Back

Speed is scalar (magnitude only), while velocity is vector (magnitude and direction).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the unit of force in the SI system?

Back

Newton (N)

Front

What does a flat line on a distance-time graph indicate?

Back

The object is at rest.
