Physics Final Exam

Front

What is the principle of free fall?

Back

In the absence of air resistance, all objects fall at the same rate regardless of their mass, due to gravity.

Front

Define acceleration in physics.

Back

Front

What does inertia refer to?

Back

Inertia is the tendency of an object to resist changes in its state of motion; objects in motion stay in motion, and objects at rest stay at rest.

Front

What is the relationship between force and mass according to Newton's second law?

Back

Front

What is net force?

Back

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

Front

How do you calculate net force when multiple forces are acting in opposite directions?

Back

Subtract the smaller force from the larger force and apply the direction of the larger force.

Front

What is the formula for calculating gravitational force?

Back

Front

What is the significance of the acceleration due to gravity?

Back

Front

Explain the concept of mass in physics.

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is the difference between mass and weight?
