DB Mid-term Exam part 2

Front

What is Newton's Second Law of Motion?

Back

The formula for Newton's Second Law of Motion is F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration.

Front

What does Newton's 1st Law of Motion state?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

How does increasing mass affect acceleration?

Back

If you increase the mass of an object while keeping the force constant, its acceleration decreases.

Front

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

Back

The relationship is defined by Newton's Second Law: F = ma.

Front

What happens to an object in motion if no net force acts on it?

Back

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

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A magician pulling a tablecloth from under dishes without moving them demonstrates Newton's 1st Law.

Front

What are high tides caused by?

Back

High tides are caused by the gravitational pull of the moon and the sun on Earth's oceans.

Front

If the moon is in position X, where would high tides occur?

Back

High tides would occur at locations Z and X.
