Semester Review Pt 2

The gravitational force between Earth and the satellite decreases.

The initial horizontal speed and the time of flight determine the horizontal distance.

The normal force is equal to the weight of the object if there are no vertical forces acting on it.

Centripetal force is the net force acting towards the center of a circular path, keeping the object in circular motion.

Use the formula t = √(2h/g), where h is the height and g is the acceleration due to gravity.

The gravitational force is directly proportional to the mass of the object.

The initial vertical speed determines the maximum height and time of flight of the projectile.

The optimal angle for maximum range is 45 degrees in a vacuum.

Air resistance decreases the range and height of the projectile compared to motion in a vacuum.

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