Study Notes
Learning Targets
- Understand the relationship between force, mass, and motion.
- Investigate how force applied and mass affect an object's motion.
- Recognize that when one body exerts a force on another, an equal force is exerted back on it.
Concepts of Force
- Force is defined as the ability to push or pull an object with mass.
- It acts on an object to change its velocity.
Effects of Force
- A stationary object can be set into motion by an applied force.
- The direction of a moving object can be altered through the application of force.
- Applied force can halt the movement of an object.
Force Direction
Forces Acting in the Same Direction
- Forces acting in the same direction combine to increase the total force on an object.
Forces Acting in Opposite Directions
- Forces acting in opposite directions result in a net force that is the difference between them.
Balanced vs. Unbalanced Forces
- Balanced forces result in no change to an object's motion.
- Unbalanced forces cause an object to accelerate in the direction of the larger force.
Application Questions
- Analyze the state of forces acting on an object, such as determining if forces on a box are balanced or unbalanced.
- Consider the effects of ceasing to apply force, such as the change in movement of the box when the force is stopped.
Nature of Force
- Force is the ability to push or pull an object with mass.
- It causes changes in an object's velocity, which includes starting, stopping, or changing direction.
Effects of Force
- Can place a stationary body in motion.
- Can change the direction of a moving object.
- Can stop a moving body.
Forces Involve Directions
- Same Direction: When two forces act together in the same direction, their effects are combined (added).
- Opposite Direction: When two forces act in opposite directions, they cancel each other out to some extent (subtracted).
