8.6 A Force

Front

What is the formula to calculate net force?

Back

Net Force (F) = Mass (m) × Acceleration (a)

Front

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

Back

The unit of force is the Newton (N).

Front

If an object has a mass of 10 kg and accelerates at 2 m/s², what is the net force acting on it?

Back

20 N (calculated using F = m × a).

Front

What happens to the acceleration of an object if the net force acting on it increases while its mass remains constant?

Back

The acceleration increases.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect the acceleration of an object when a constant force is applied?

Back

Greater mass results in lower acceleration for the same force (F = m × a).

Front

What is the relationship between force, mass, and acceleration?

Back

Force is directly proportional to mass and acceleration (F = m × a).

Front

If a skateboarder pushes with a force of 25 N and the wind pushes back with 8 N, what is the net force?

Back

The net force is 17 N (25 N - 8 N).

Front

What is the effect of balanced forces on an object's motion?

Back

Balanced forces do not change the object's motion; it remains at rest or in constant motion.

Front

What is the effect of unbalanced forces on an object's motion?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.
