Calculating Net Force

Front

What is net force?

Back

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

Front

What unit do scientists use to measure force?

Back

Newtons (N) are the units used to measure force.

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What force opposes motion between two surfaces?

Back

Friction is the force that opposes motion between two surfaces.

Front

What happens to an object when unbalanced forces act on it?

Back

An object will accelerate, decelerate, or change direction when unbalanced forces act on it.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does gravity affect motion?

Back

Gravity pulls objects toward the Earth, affecting their motion and speed.

Front

What is the formula for calculating net force?

Back

Net force = Total forces acting in one direction - Total forces acting in the opposite direction.

Front

What is an example of balanced forces?

Back

A book resting on a table is an example of balanced forces; the force of gravity is balanced by the support force of the table.
