8.6 A Force

Front

What is the formula to calculate net force?

Back

Net Force (F) = Mass (m) x 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

How do you calculate acceleration?

Back

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

Front

What is inertia?

Back

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

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

If a force of 10 N is applied to a 2 kg object, what is its acceleration?

Back

Acceleration = 10 N ÷ 2 kg = 5 m/s².

Front

What happens to the acceleration of an object if the net force acting on it is doubled?

Back

The acceleration will also double, assuming mass remains constant.

Front

What is the effect of balanced forces on an object?

Back

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

Front

What is the effect of unbalanced forces on an object?

Back

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

Front

What is the formula for calculating force when mass and acceleration are known?

Back

Force (F) = Mass (m) x Acceleration (a).
