Newton's Laws

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F = M x A.

What does the term 'force' mean in physics?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is an example of balanced forces?

Back

A book resting on a table is an example of balanced forces, as the force of gravity pulling the book down is balanced by the normal force from the table pushing it up.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is an example of unbalanced forces?

Back

A pencil being knocked off a desk is an example of unbalanced forces, as the force of the hand knocking it off is greater than the force of gravity holding it in place.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = M x A, where F is force, M is mass, and A is acceleration.

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.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).
