Newton Laws

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction 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 (F = ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

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

What is net force?

Back

Net force is the vector sum of all the forces acting on an object.

Front

How do you determine the direction of motion when forces are unbalanced?

Back

The object will move in the direction of the larger force.

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 a 20 kg bike accelerates at 10 m/s², what is the force acting on it?

Back

The force is 200 Newtons, calculated using F = ma (F = 20 kg * 10 m/s²).

Front

What happens to an object when the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is inertia?

Back

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