Answer:
Situation -- Predicted Motion
How is motion predicted?
Newton's second law of motion says that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. You can use it to predict the motion of an object. The net force is the vector sum of all the forces that act on the object.
Rolling down an open
space
What causes an object to roll down a ramp?
When you lift an object up off the ground, it has potential energy due to gravity. So when you roll a ball down a ramp, it has the most potential energy when it is at the top, and this potential energy is converted to both translational and rotational kinetic energy as it rolls down.
Throwing in the air
Analyzing motion for objects in freefall
For example, when a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum heigh.
Dropping on the floor
The force of gravity causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called the acceleration due to gravity. ... The direction of the acceleration due to gravity is downward (towards the center of Earth). In fact, its direction defines what we call vertical.
