Forces and Newton's Law

Front

What is the definition of force?

Back

A force is a push or pull acting upon an object, resulting from its interaction with another object.

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 inertia?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × acceleration due to gravity (g), where g is approximately 9.8 m/s² on Earth.

Front

What is the relationship 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 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 Newton's Third Law of Motion?

Back

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

Front

How does gravity affect objects in free fall?

Back

All objects in free fall experience the same acceleration due to gravity, regardless of their mass.

Front

What is tension in a rope or cable?

Back

Tension is the force transmitted through a rope, string, or cable when it is pulled tight by forces acting from opposite ends.
