Kinematics review worksheet #1 writing and balancing formula equations answers

Matter is conserved because atoms are conserved in physical and chemical processes. MS-PS - Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

Kinematics review worksheet #1 writing and balancing formula equations answers

Which of the following statements about free fall and the acceleration of gravity are TRUE? List all that apply. An object that is free-falling is acted upon by the force of gravity alone. A falling skydiver which has reached terminal velocity is considered to be in a state of free fall.

A ball is thrown upwards and is rising towards its peak. As it rises upwards, it is NOT considered to be in a state of free fall. An object in free fall experiences an acceleration which is independent of the mass of the object.

A ball is thrown upwards, rises to its peak and eventually falls back to the original height. As the ball rises, its acceleration is upwards; as it falls, its acceleration is downwards.

The speed at which it is launched equals the speed at which it lands. Assume negligible air resistance.

A very massive object will free fall at the same rate of acceleration as a less massive object. The value of g on Earth is approximately 9. The symbol g stands for the force of gravity. This is the definition of free fall. FALSE - Skydivers which are falling at terminal velocity are acted upon by large amounts of air resistance.

They are experiencing more forces than the force of gravity. As such, they are NOT free-falling. FALSE - Any object - whether rising, falling or moving horizontally and vertically simultaneously - can be in a state of free fall if the only force acting upon it is the force of gravity.

Such objects are known as projectiles and often begin their motion while rising upwards.

TRUE - The unique feature of free-falling objects is that the mass of the object does not effect the trajectory characteristics. The acceleration, velocity, displacement, etc. A rising object slows down due to the downward gravity force.

An upward-moving object which is slowing down is said to have a downwards acceleration. TRUE - If the object is truly in free-fall, then the speed of the object will be the same at all heights - whether its on the upward portion of its trajectory or the downwards portion of its trajectory.

For more information, see the Projectiles page at The Physics Classroom. TRUE - The acceleration of free-falling objects referred to as the acceleration of gravity is independent of mass. On Earth, the value is 9. All objects - very massive and less massive - experience this acceleration value.

It might be best to call it the acceleration caused by gravity. When it comes to the force of gravity, we have yet another symbol for that - Fgrav.A 1 m step will increase the displacement (read as out of place-ness) by 1 meter and contribute one more meter to the total distance which is walked.
