Net Force and Acceleration

Front

What is Net Force?

Back

Net Force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

How do you calculate Net Force?

Back

Net Force (F_net) = Sum of all forces acting on an object. If forces are in opposite directions, subtract the smaller force from the larger one.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F_net) / Mass (m). It shows how much the velocity of an object changes over time.

Front

What is the unit of force?

Back

The unit of force is the Newton (N). It is defined as the force required to accelerate a 1 kg mass by 1 m/s².

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down or decelerating.

Front

If an object has a mass of 10 kg and experiences a net force of 20 N, what is its acceleration?

Back

Acceleration = Net Force / Mass = 20 N / 10 kg = 2 m/s².

Front

What is the effect of balanced forces on an object?

Back

Balanced forces result in a net force of 0 N, meaning the object will remain at rest or continue moving at a constant velocity.

Front

What happens when forces are unbalanced?

Back

Unbalanced forces result in a net force greater than 0 N, causing the object to accelerate in the direction of the net force.

Front

In a tug of war, if Team A pulls with 100 N to the right and Team B pulls with 120 N to the left, what is the net force?

Back

Net Force = 120 N (left) - 100 N (right) = 20 N to the left.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through air, often acting upward against the force of gravity.
