Motion In A Straight Line Flashcards
What is the field of physics that investigates the motion of tangible objects?
Mechanics
Mechanics is a crucial area in physics that deals with the behavior of physical bodies when subjected to forces or displacements.
What are the three main branches of mechanics?
- Statics
- Kinematics
- Dynamics
These branches address different aspects of motion and forces.
What is statics concerned with?
The study of real-world objects at rest.
What does kinematics study?
How physical objects move without considering the forces that propel them.
What does dynamics study?
How physical objects move while taking the causes of movement into account.
How is an object defined as being at rest?
When it remains in the same position in relation to its surroundings.
How is motion defined?
When an object shifts in relation to its surroundings.
True or False: Motion and rest are absolute states.
False
Motion and rest are relative and depend on the observer’s frame of reference.
What is a point mass object?
An object that travels over distances significantly larger than its own size.
What is the position of an object relative to?
A reference point, typically referred to as the origin.
Define distance in the context of motion.
The path that the object actually takes when moving.
Define displacement in motion.
The discrepancy between an object’s starting and ending positions during motion.
What is true about displacement when an object moves in a straight line in the same direction?
The magnitude of displacement and the total route length are equal.
What is the average velocity?
The displacement divided by the time period of that displacement.
What is the average speed?
The total path length travelled divided by the total time of motion.
What characterizes uniform motion?
A body travels the same distances in the same amounts of time, indicating constant velocity.
What characterizes non-uniform motion?
A body travels different distances in different amounts of time, indicating variable velocity.
