Flashcards on Kinematics and Dynamics

Click on the flashcard to see the answer


What is kinematics?

The branch of physics that deals with the motion of objects.

What is dynamics?

The branch of physics that deals with the forces and motion of objects.

What is the formula for velocity?

Velocity = Distance / Time

What is acceleration?

The rate of change of velocity.

What is the equation for acceleration?

Acceleration = (Final Velocity - Initial Velocity) / Time

What is the net force?

The overall force acting on an object.

What is Newton's first law of motion?

An object at rest will stay at rest, and an object in motion will stay in motion with the same velocity, unless acted upon by an external force.

What is Newton's second law of motion?

The force acting on an object is equal to the mass of the object multiplied by its acceleration.

What is Newton's third law of motion?

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

What is the formula for force?

Force = Mass x Acceleration

What is the difference between speed and velocity?

Speed is a scalar quantity that only indicates how fast an object is moving, while velocity is a vector quantity that specifies both the speed and direction of an object's motion.

What is the unit for force?

The unit for force is the Newton (N).

What is the formula for momentum?

Momentum = Mass x Velocity

What is the role of friction in dynamics?

Friction is a force that opposes the motion of objects and plays a crucial role in dynamics.

What is the formula for work?

Work = Force x Distance
