Calculating Net Force Test Review

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object does not accelerate; it either remains at rest or continues moving at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the greater force.

Front

If a cart has a mass of 6 kg and experiences a net force of 15 N to the left, what is the acceleration?

Back

Acceleration = Net Force / Mass = 15 N / 6 kg = 2.5 m/s² to the left.

Front

In a tug-of-war, if one group pulls with 400 N and the other with 250 N, which group wins?

Back

The group pulling with 400 N wins, and the ribbon moves to the right.

Front

What is the formula to calculate net force?

Back

Net Force = Force1 + Force2 + ... + ForceN (considering direction).

Front

What is an example of balanced forces?

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?

Back

A soccer ball being kicked experiences unbalanced forces, resulting in acceleration in the direction of the kick.

Front

If two forces of 10 N to the right and 5 N to the left act on an object, what is the net force?

Back

Net Force = 10 N (right) - 5 N (left) = 5 N to the right.

Front

What is the effect of a net force of zero on an object?

Back

An object with a net force of zero will not change its state of motion; it will remain at rest or continue moving at a constant velocity.
