What is the purpose of using arrows to represent forces?
To show the direction and magnitude of the force
When measuring force using a spring balance, what determines the distance the spring moves?
The size of the force applied
What is the difference between contact forces and non-contact forces?
Contact forces require physical contact, non-contact forces do not

Which of the following forces would not be considered a contact force?
Gravitational force
What is the key difference between contact and non-contact forces?
Contact forces require physical contact, while non-contact forces do not
According to Hooke's Law, what is the relationship between the force applied to a spring and its resulting movement?
The distance a spring moves is directly proportional to the force applied
What is the correct way to calculate the net force acting on an object?
Add the forces acting in one direction and subtract the forces acting in the opposite direction
What is an example of an object exerting a force on another object without physical contact?
A magnet attracting a paper clip
Why do we use arrows to represent forces in diagrams?
To indicate the direction and magnitude of the force
What determines the direction of the net force acting on an object?
The combination of forces acting in one direction and subtracting the forces acting in the opposite direction
What happens when an object's velocity changes over time due to a force, and its acceleration is zero?
The object's velocity remains constant
What is the result of an object exerting a force on another object without touching, according to Newton's Third Law of Motion?
The second object exerts an equal and opposite force on the first object
What is the net force when multiple forces act on an object, and their combined effect is zero?
Zero, because the forces are balanced
What happens when a force is applied to an object, and its shape changes, but its motion remains constant?
The force is only acting on the object's shape
