Calculating Net Force Test Review

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration and direction of motion.

Front

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

Back

To calculate net force when multiple 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 and take the direction of the larger force.

Front

What does it mean if the net force is zero?

Back

If the net force is zero, the forces acting on the object are balanced, and the object will remain at rest or continue to move at a constant velocity.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

In a tug-of-war, what happens if one team exerts a greater force than the other?

Back

If one team exerts a greater force than the other, the net force will be in the direction of the stronger team, causing the weaker team to move in that direction.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

Front

How does mass affect the net force acting on an object?

Back

The mass of an object affects its acceleration when a net force is applied, as described by Newton's second law (F=ma). A larger mass requires a greater force to achieve the same acceleration.

Front

What is the relationship between net force and acceleration?

Back

According to Newton's second law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F=ma).

Front

What is the effect of friction on net force?

Back

Friction is a force that opposes motion. It can reduce the net force acting on an object, affecting its acceleration and direction.
