HW #3 - Net Force and Acceleration Flashcardizz

Front

What is net force?

Back

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

Front

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

Back

Add the magnitudes of the forces together.

Front

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

Back

Subtract the smaller force from the larger force and take the direction of the larger force.

Front

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

Back

The unit of force is the Newton (N).

Front

What is the relationship between net force and acceleration according to Newton's second law?

Back

The net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

If an object has a net force of 0 N, what can be said about its motion?

Back

The object is either at rest or moving at a constant velocity.

Front

What is the effect of increasing the mass of an object on its acceleration if the net force remains constant?

Back

Increasing the mass will decrease the acceleration, as acceleration is inversely proportional to mass (a = F/m).

Front

If two forces of 10 N and 6 N act in the same direction, what is the net force?

Back

The net force is 16 N in the same direction.

Front

If a force of 20 N acts to the right and a force of 15 N acts to the left, what is the net force?

Back

The net force is 5 N to the right.

Front

What is the net force when two people push a car with forces of 200 N east and 150 N east?

Back

The net force is 350 N east.
