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 the relationship between mass and inertia?

Back

Objects with greater mass have greater inertia.

Front

What is the unit of force?

Back

The unit of measurement for force is Newtons.

Front

What factors affect friction?

Back

Friction depends on the weight of the objects pressing together and the nature of the surfaces in contact.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

How does mass affect acceleration?

Back

For a given force, an increase in mass results in a decrease in acceleration.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.
