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

Front

What happens to the gravitational force between two planets as they move farther apart?

Back

The gravitational force decreases.

Front

What is the relationship between distance and gravitational force?

Back

As the distance separating the objects increases, the gravitational force decreases.

Front

What is the Law that states all objects in the universe attract each other through gravitational force?

Back

The Law of Universal Gravitation.

Front

What two factors does the momentum of an object depend on?

Back

Mass and velocity.

Front

What is defined as a PUSH or PULL of an object?

Back

Force.

Front

What is the formula for calculating momentum?

Back

Momentum = mass × velocity.

Front

What is the effect of mass on gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.

Front

What is Kinematics?

Back

The branch of physics that describes the motion of objects without considering the forces that cause the motion.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².
