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 when two forces act in opposite directions?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula: a = net force (F) / mass (m).

Front

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

Back

Acceleration = 20 N / 10 kg = 2 m/s².

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration compared to free fall.

Front

What happens to the net force if two people push a cabinet with equal forces in opposite directions?

Back

The net force is zero, as the forces cancel each other out.

Front

If a car is pushed with a force of 300 N east and another force of 200 N east, what is the net force?

Back

Net force = 300 N + 200 N = 500 N east.

Front

What is the significance of a negative acceleration?

Back

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

Front

How does mass affect acceleration when a constant force is applied?

Back

Greater mass results in lower acceleration for the same applied force, according to Newton's second law.

Front

What is the relationship between net force and motion?

Back

Net force determines the motion of an object; if net force is zero, the object remains at rest or in uniform motion.
