Physics: Motion and Speed

A set of flashcards designed to help understand key concepts related to motion and speed in physics.

Accelerated Motion

A type of motion in which the velocity of an object changes over time.

Average Speed

The total distance traveled divided by the total time taken.

Acceleration Symbol & Unit

Symbol: a; Unit: m/s².

Velocity Symbol & Unit

Symbol: v; Unit: m/s.

Distance Symbol & Unit

Symbol: s; Unit: m.

Time Symbol & Unit

Symbol: t; Unit: s.

Calculating Speed

Speed can be calculated by dividing the distance by time.

Uniform Motion

Motion at a constant speed in a straight line.

Curvilinear Motion

Motion along a curved path.

Instantaneous Velocity

The velocity of an object at a specific moment in time.

Decelerated Motion

A type of motion in which an object's velocity decreases over time.

What is 1 m/s in km/h?

1 m/s is equivalent to 3.6 km/h.

What is on the vertical axis?

Typically represents distance or displacement.

What is on the horizontal axis?

Typically represents time.

What is motion?

The change of position of an object over time.

What falls under motion?

Any change in the position of an object.

How do you calculate average speed?

Total distance divided by total time.

How do you calculate accelerated motion?

Change in velocity divided by time.

How do you calculate uniform motion?

Distance over time, remaining constant.

How do you calculate decelerated motion?

Initial velocity minus final velocity divided by time.

How is velocity indicated?

Velocity is expressed in meters per second (m/s).
