Newtons laws

Front

What is Newton's 1st Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an unbalanced force.

Front

What does inertia refer to in physics?

Back

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

Front

What is Newton's 2nd Law of Motion?

Back

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

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

When the force is constant, an increase in mass results in a decrease in acceleration.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

Define mass in the context of physics.

Back

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

Front

What is the difference between mass and weight?

Back

Mass is a measure of the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What type of friction requires the most force to overcome?

Back

Gliding friction requires more force to overcome than rolling or fluid friction.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

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

Back

The relationship is described by Newton's 2nd Law: Force equals mass times acceleration (F = ma).
