Net Force

Front

What is the unit for force?

Back

N (Newtons)

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no net force.

Front

How do you calculate net force when multiple forces are acting on an object?

Back

Add the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

If a force of 100N is acting to the right and a force of 40N is acting to the left, what is the net force?

Back

60N, Right

Front

What is the principle of superposition in the context of forces?

Back

The principle of superposition states that the net force acting on an object is the vector sum of all individual forces acting on it.

Front

What is the difference between contact forces and non-contact forces?

Back

Contact forces require physical contact between objects, while non-contact forces act at a distance (e.g., gravitational force).

Front

What is an example of a non-contact force?

Back

Gravity is an example of a non-contact force.

Front

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

Back

The net force is zero, resulting in no acceleration.

Front

What is the formula for calculating net force?

Back

Net Force = Sum of Forces acting in one direction - Sum of Forces acting in the opposite direction.

Front

What does it mean if an object is in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero.
