Kinematics and Projectile Motion

These flashcards cover essential concepts in kinematics and projectile motion, including definitions, differences, and factors affecting motion.

What is kinematics?

The study of motion using equations.

What is the difference between distance and displacement?

Distance is the total length travelled, while displacement is the shortest distance from initial to final position.

Define speed and velocity.

Speed is the rate at which an object covers distance; velocity is the rate of change of displacement over time.

What is acceleration?

The rate of change of velocity.

What is projectile motion?

A form of motion where an object given an initial velocity is thrown and is acted upon by gravity, following a curved path.

What are the parts of projectile motion?

Initial velocity, projectile, and trajectory.

What factors affect the height and range of a projectile's trajectory?

Angle of launch and initial velocity.

What is momentum?

Momentum is the product of mass and velocity; it is mass in motion.

What is impulse?

The change in momentum of an object.

How do mass and velocity affect momentum?

The greater the mass and the faster the velocity, the greater the momentum.

What happens to the momentum of a bus traveling through curvy roads?

The momentum of the bus changes due to the change in direction and velocity.

If a car and a bus are traveling at the same velocity, which has greater momentum if the bus has more passengers?

The bus has greater momentum due to its greater mass.

What is the trajectory of a projectile?

The parabolic path taken by a projectile.
