Newtons Laws of Motion

Front

What is Newton's 1st 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 2nd 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.

What is Newton's 3rd Law of Motion?

Back

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

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

What is the formula for calculating force?

Back

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

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is the unit of force?

Back

The unit of force is the Newton (N), which is defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

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.

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

As mass increases, for a given force, the acceleration decreases.

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.
