Force and Motion

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 acceleration?

Back

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

What is inertia?

Back

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

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

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 (F=ma).

What is Newton's Third Law of Motion?

Back

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

Front

What factors affect the acceleration of an object?

Back

The net force acting on the object and the mass of the object affect its acceleration.

What is the formula for calculating force?

Back

Force is calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.
