Newton's Laws, Gravity, Kinematics, Momentum (Final, Pt 1 of 2)

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 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

What is gravitational force?

Back

The attractive force between two masses, described by the equation F = G(m1*m2)/r^2.

Front

What does the variable 'G' represent in the gravitational force equation?

Back

G is the gravitational constant, approximately equal to 6.67 x 10^-11 (N*m^2)/kg^2.

Front

How do you calculate gravitational force between two objects?

Back

Use the formula F = G(m1*m2)/r^2, where m1 and m2 are the masses of the objects and r is the distance between their centers.

Front

What does a velocity vs. time graph represent?

Back

It shows how the velocity of an object changes over time.

Front

What does a position vs. time graph indicate?

Back

It shows the position of an object at various times, indicating its motion.

Front

What does a flat line on a position vs. time graph mean?

Back

The object is not moving.

Front

What does a straight diagonal line on a position vs. time graph indicate?

Back

The object is moving with constant velocity.
