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 the formula to calculate force?

Back

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

Front

What is inertia?

Back

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

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

The acceleration decreases.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight (W) = mass (m) × gravitational acceleration (g).

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, affecting their acceleration and terminal velocity.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by air resistance.

Front

How does Newton's 1st Law apply to a skateboard rolling on a flat surface?

Back

The skateboard will continue to roll in a straight line at a constant speed unless acted upon by an external force (like friction or a push).
