Newton's Laws of Motion

Front

What is the tendency of an object to stay in motion or at rest called?

Back

Inertia

Front

What is the net force on a book weighing 4 N when held at rest in your hands?

Back

0 N

Front

What does Newton's second law state about the acceleration produced by a net force on an object?

Back

The acceleration is directly proportional to the net force and inversely proportional to the mass of the object.

Front

What does it mean when an object is moving at a fast steady speed?

Back

It is moving away from the starting position with constant velocity.

Front

What is the difference between mass and weight?

Back

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

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 unless acted upon by a net external force.

Front

How does mass affect the acceleration of an object when a net force is applied?

Back

Greater mass results in less acceleration for the same net force, according to Newton's second law.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = mg).

Front

What is the role of friction in motion according to Newton's laws?

Back

Friction opposes the motion of an object and can affect its acceleration.

Front

What is the significance of the net force in determining an object's motion?

Back

The net force determines the acceleration and direction of an object's motion.
