Review: Force Diagrams & Motion

Front

What is a force diagram?

Back

A visual representation that shows all the forces acting on an object, including their direction and magnitude.

Front

What does it mean when an object is accelerating?

Back

It means the object's velocity is changing, which can be an increase or decrease in speed or a change in direction.

Front

What is the net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

How do you determine the direction of motion from a force diagram?

Back

The direction of the net force indicates the direction of motion; if the net force is not zero, the object will accelerate in that direction.

Front

What happens to an object at rest when a net force is applied?

Back

The object will start to move in the direction of the net force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net force.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion (net force = 0), while unbalanced forces cause an object to accelerate.

Front

What does it mean for an object to be in free fall?

Back

An object is in free fall when the only force acting on it is gravity, causing it to accelerate downward.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes motion between two surfaces in contact, affecting the acceleration of an object.

Front

How can you represent forces in a force diagram?

Back

Forces are represented by arrows; the length indicates the magnitude, and the direction indicates the direction of the force.
