Newton's 1st and 2nd Laws

Front

What is Newton's First Law known as?

Back

The Law of Inertia.

Front

What does Newton's First Law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law?

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 formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is inertia?

Back

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

Front

What is normal force?

Back

A force from a surface that is always perpendicular to the surface.

Front

What force opposes the motion of objects?

Back

Friction.

Front

What happens when forces are balanced?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

The object will accelerate in the direction of the net force.

Front

What is the role of gravity in motion?

Back

Gravity pulls objects toward the center of the Earth, affecting their weight and motion.
