Force Mass and Acceleration

Front

What is Newton's second law of motion?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F=MA.

Front

What does the term 'net force' mean?

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 acceleration?

Back

Acceleration can be calculated using the formula A = F/M, where A is acceleration, F is net force, and M is mass.

Front

What is the relationship between mass and acceleration?

Back

Mass and acceleration are inversely related; as mass increases, acceleration decreases if the force remains constant.

Front

If a force of 10 N is applied to a mass of 2 kg, what is the acceleration?

Back

Using the formula A = F/M, acceleration is 10 N / 2 kg = 5 m/s².

Front

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

Back

The unit of force is the Newton (N).

Front

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

Back

If the net force is zero, the object will not accelerate; it will either remain at rest or continue moving at a constant velocity.

Front

What factors affect the acceleration of an object?

Back

The acceleration of an object is affected by the net force acting on it and its mass.

Front

If a 5 kg object experiences a net force of 20 N, what is its acceleration?

Back

Using the formula A = F/M, acceleration is 20 N / 5 kg = 4 m/s².

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.
