Net forces flashcard review

Front

What is a force?

Back

A force is a push or pull on an object.

Front

What is the net force?

Back

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

Front

How do you calculate net force when forces are acting in the same direction?

Back

To calculate net force when forces are acting in the same direction, you add their magnitudes together.

Front

How do you calculate net force when forces are acting in opposite directions?

Back

To calculate net force when forces are acting in opposite directions, you subtract the smaller force from the larger force.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What does a net force of 0 N indicate about an object's motion?

Back

A net force of 0 N indicates that the object is in equilibrium and will not accelerate; it may be at rest or moving at a constant velocity.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the force that holds planets in motion around the sun.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is the formula for calculating weight?

Back

Weight can be calculated using the formula: Weight = mass × gravitational acceleration (W = m × g).
