Module 4 Review

An Earth satellite in an elliptical orbit travels fastest when it is

According to Newton, the greater the masses of interacting objects, the

The conservation of energy applies to satellites in

An Earth satellite is simply a projectile

As soon as a bowling ball rolls off the edge of a table its horizontal component of velocity

The tangential velocity of an Earth satellite is its velocity

Nellie tosses a ball upward at an angle. Assuming no air resistance, which component of velocity changes with time?

Surrounding a magnet is a magnetic field. Surrounding an electron is an electric field. Surrounding Earth is

The difference between Newton's law as a proportion and an equation involves

According to Newton, when the distance between two interacting objects doubles, the gravitational force is

A dropped ball gains speed because

If Earth's radius somehow increased with no change in mass, your weight would

The identities of dark energy and dark matter are

If a satellite's radial velocity is zero at all times, its orbit must be

Which is most responsible for Earth's ocean tides?

Wobbles in the path of Uranus led to the discovery of

If a space capsule moves to twice its distance from Earth, the force of gravity becomes

What is the force of gravity on a 500-N woman standing on Earth's surface?

The universal gravitational constant G was first measured

A black hole is

Both Newton and Kepler considered forces on the planets. Kepler mistakenly thought the direction of the forces to be

The direction of a gravitational field is

A ball launches horizontally from a bench. If the speed of the ball were greater, the time in the air would be

Planets would crash into the Sun if it weren't for

Pluto is classified by as a

Planets wobble in their orbits due to

According to Kepler, the line from the Sun to any planet sweeps out equal areas of space

When the potential energy of a satellite decreases

As soon as a ball rolls off the edge of a table

The radial velocity of an Earth satellite is its velocity

A ball rolled along a horizontal surface maintains a constant speed because

According to Kepler, the paths of planets about the Sun are

According to Kepler, the orbital period of a planet is directly proportional to the

Who envisioned the motion of planets as projectiles obeying the laws of physics?

An outcome of universal gravitation is that

Newton hypothesized that the forces acting on planets was

A ball rolls off a table at the same time another ball drops from the same table. The ball to hit the floor first is the

A projectile is launched upward at 50 m/s. Without air resistance, its speed upon returning to its starting point is

Earth's gravitational field extends

According to Kepler, the speed of a planet is slowest when it is

The main reason ocean tides exist is that Moon's pull is stronger

If the mass of Earth somehow increased with no change in radius, your weight would

In comparison with other fundamental forces, the universal gravitational constant G indicates that gravity is

Newton discovered

If a space capsule moves to half its distance from Earth, the force of gravity becomes

When Kepler devised his laws of planetary motion, he was most influenced by
