balanced forces and free body diagrams

• What happens to the speed of an object when all the forces on it are balanced?

  The speed of the object remains the same.
• What does it mean when the speed of an object is 0 m/s?

  It indicates that the object is at rest.
• What occurs when all the forces on an object are unbalanced?

  The speed of the object changes.
• What are the possible changes in speed when forces on an object are unbalanced?

  The object can either speed up, slow down, or change direction.
• What does Newton's First Law state?

  A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force.
• What does Newton's Second Law describe?

  If a body is acted upon by a force, the object will accelerate, changing its speed or direction.
• What is a free body diagram?

  A free body diagram shows the forces acting on an object.
• How should an object be represented in a free body diagram?

  It can be represented as a spot, regardless of its shape.
• What does it indicate if the forces in a free body diagram are the same size?

  It indicates that the forces are balanced.
• what does a free body diagram look like


  it has a dot in the middle with 90 degree angles coming out of it, showing the different forces surrounding the object
