A force is a push or a pull that acts on an object due to the interaction with another object. Force is measured in newtons (N). Forces are divided into contact forces and non-contact forces.
According to the work-energy theorem, when a force acts upon a body while that body moves along the line of the force, the force does work upon the body, and the amount of work done is equal to the change in the body's kinetic energy.

- Applying Free Fall Concepts to Problem-Solving
- Example Problem A
- Example Problem B
There are a few conceptual characteristics of free fall motion that will be of value when using the equations to analyze free fall motion. These concepts are described as follows: 1. An object in free fall experiences an acceleration of -9.8 m/s/s. (The - sign indicates a downward acceleration.) Whether explicitly stated or not, the value of the ac...
Luke Autbeloe drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground. The solution to this problem begins by the construction of an informative diagram of the physical situation. This is shown below. The second step involves the identification and l...
Rex Things throws his mother's crystal vase vertically upwards with an initial velocity of 26.2 m/s. Determine the height to which the vase will rise above its initial height. Once more, the solution to this problem begins by the construction of an informative diagram of the physical situation. This is shown below. The second step involves the iden...
A force is a push or pull that acts upon an object as a result of that objects interactions with its surroundings. In this Lesson, The Physics Classroom differentiates between the various types of forces that an object could encounter. Some extra attention is given to the topic of friction and weight.
