Understanding Newton's Laws: SUM IT UP

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 an unbalanced force.

Front

What is the formula to calculate force?

Back

Force (F) = Mass (m) × Acceleration (a)

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is inertia?

Back

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

Front

What does the term 'net force' mean?

Back

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

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.

Front

What is the significance of the direction of a force?

Back

The direction of a force determines how it will affect the motion of an object.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is gravity?

Back

Gravity is a force of attraction between two masses.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.
