An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

What is Newton's second law of motion?

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

What is Newton's third law of motion?

For every action, there is an equal and opposite reaction.

What is inertia?

The tendency of an object to resist changes in its motion.

What is the formula for force?

Force = mass x acceleration

What is the unit of force?

Newton

What is the difference between mass and weight?

Mass is the amount of matter in an object, while weight is the force of gravity acting on an object.

What is the relationship between force, mass, and acceleration?

Force is equal to mass multiplied by acceleration.

What is the law of conservation of momentum?

The total momentum of a closed system remains constant if no external forces are acting on it.

What is the difference between balanced and unbalanced forces?

Balanced forces result in no change in motion, while unbalanced forces cause acceleration.

What is the role of friction in motion?

Friction opposes the motion of objects and can cause them to slow down or come to a stop.

What is the law of universal gravitation?

Every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

What is the difference between speed and velocity?

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that refers to the rate at which an object changes its position.

What are contact forces?

Contact forces are forces that result from the physical interaction between objects.

What are non-contact forces?

Non-contact forces are forces that can act on an object without touching it.

What is the principle of conservation of energy?

Energy cannot be created or destroyed, only transferred or transformed from one form to another.

What is Newton's first law of motion?

An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
