Force Diagrams Flashcards
What is the definition of measurement?
The action of measuring something
Measurement is crucial in various scientific contexts.
What is a Force Diagram?
A simple drawing that shows all the forces acting on an object
Forces are represented by arrows indicating size and direction.
What do the length and direction of the arrows in a force diagram represent?
The length shows the size of the force, and the direction shows which way the force is acting
For example, pushing a box shows the force direction with an arrow.
What are contact forces?
Forces that happen when two objects are touching
Examples include friction, tension, and normal force.
What are non-contact forces?
Forces that happen without touching
Examples include gravity and magnetic force.
How is resultant force calculated?
Add up all the forces while paying attention to their directions
Forces in the same direction are added, while opposite forces are subtracted.
What happens if the forces acting on an object are balanced?
There is no movement
Balanced forces are equal in size but opposite in direction.
What should be included when drawing a force diagram?
Draw the object and represent each force with an arrow
The size of the arrow matches the strength of the force and the direction shows where the force is acting.
What forces might be involved when a person pushes a shopping cart?
- Friction between the wheels and the ground
- The force of the person pushing
- Gravity pulling the cart down
A force diagram helps visualize how these forces interact.
True or False: Force diagrams are only useful in scientific contexts.
False
They also help us understand everyday situations and interactions.
Fill in the blank: The gravitational force pulls objects ______ the Earth.
toward
Gravity is a key non-contact force.
