Newton Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is the definition of mass?

Back

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

Front

What is the definition of force?

Back

Force is an interaction that causes an object to change its velocity, measured in Newtons (N).

Front

What is Newton's Second 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

What is the definition of acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is a balanced force?

Back

A balanced force occurs when the net force acting on an object is zero, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate.

Front

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

Back

The relationship is described by Newton's Second Law: F = ma, where F is force, m is mass, and a is acceleration.

Front

What happens to an object in motion if no net forces act on it?

Back

It will continue to move in a straight line at a constant speed.

Front

What is inertia?

Back

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