Newton's Second Law of Motion R2

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 (Force = mass x acceleration).

Front

How do you calculate acceleration using Newton's Second Law?

Back

Acceleration can be calculated by rearranging the formula F = ma to a = F/m, where 'a' is acceleration, 'F' is net force, and 'm' is mass.

Front

If a net force of 32 N is applied to a 5 kg object, what is the acceleration?

Back

The acceleration is 6.4 m/s², calculated as a = 32 N / 5 kg.

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 is the relationship between mass and force according to Newton's Second Law?

Back

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

Front

If a 20 kg bike accelerates at 10 m/s², what is the force applied?

Back

The force is 200 Newtons, calculated as F = ma = 20 kg x 10 m/s².

Front

What happens to the acceleration of an object if the net force is doubled while the mass remains constant?

Back

The acceleration will also double, as acceleration is directly proportional to net force.

Front

If a 10 kg object has a force of 50 N applied to it, what is its acceleration?

Back

The acceleration is 5 m/s², calculated as a = 50 N / 10 kg.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

If two people push a couch with forces of 35 N and 25 N in the same direction, what is the net force?

Back

The net force is 60 N to the right.
