Newton's Laws

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 an unbalanced 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. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is air resistance?

Back

Air resistance is a type of friction that occurs when air pushes against a moving object, causing it to slow down.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a)

Front

What is the relationship between mass and force?

Back

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

Front

What is the significance of the net force?

Back

The net force is the total force acting on an object, taking into account all the individual forces acting on it.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.
