Newton's 1st and 2nd Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest unless a force is applied, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed as F = ma.

Front

What unit is used to measure force?

Back

The unit of force is the Newton (N).

Front

If the mass of an object is doubled, what happens to its acceleration if the same force is applied?

Back

The acceleration is halved.

Front

How does increasing the force applied to an object affect its acceleration?

Back

Increasing the force applied to an object increases its acceleration.

Front

What is the formula to calculate force?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

If an object has a mass of 4 kg and is accelerated at 3 m/s², what is the force applied?

Back

The force applied is 12 N (calculated using F = ma).

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases when the same force is applied.

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What is inertia?

Back

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