Net Force and Acceleration

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 multiple forces are acting in the same direction?

Back

Add the magnitudes of the forces together.

Front

If two forces of 200 N and 150 N are acting east, what is the net force?

Back

350 N east.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in m/s².

Front

If an elevator accelerates at -2.0 m/s², what does this indicate?

Back

It indicates that the elevator is decelerating or moving downward.

Front

What is the force exerted by the floor on a passenger with a mass of 85 kg in a decelerating elevator?

Back

663 N.

Front

What happens to the net force if two equal forces act in opposite directions?

Back

The net force is zero.

Front

What is the direction of net force if the forces are unbalanced?

Back

The direction of the net force is in the direction of the larger force.

Front

If a net force of 5 N is acting to the right, what can be said about the motion of the object?

Back

The object will accelerate to the right.
