Forces, Net Force & Diagrams Practice

Front

What is a force?

Back

A force is a push or pull acting upon an object, resulting from its interaction with another object.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the motion of an object.

Front

What happens when a marble rolls down a ramp?

Back

The forces acting on the marble are unbalanced, causing it to accelerate.

Front

What does it mean if an object is moving at a constant speed?

Back

If an object is moving at a constant speed, the forces acting on it are balanced.

Front

What is net force?

Back

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

Front

How do you determine the direction of net force?

Back

The direction of net force is the same as the direction of the greater force when forces are unbalanced.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the movement.

Front

What is an example of balanced forces in real life?

Back

A book resting on a table experiences balanced forces: the weight of the book downward and the normal force of the table upward.

Front

What is an example of unbalanced forces in real life?

Back

A car accelerating forward experiences unbalanced forces: the engine's force is greater than the frictional force.
