Physics: Basic 1 (Acceleration, disance-time, mass...etc)

What is speed?

• distance x time

• the rate at which an object changes position

• position toward which someone or something moves or faces

What is velocity?

• Like speed with direction

• Same as speed

• Like speed with distance

• Same as acceleration

What is displacement?

• Consequence of the unniversial law of gravitation

• A representation of both a quantity and a direction at the same time

• The difference between the final and initial position of a point trajectory

• A number which represents rthe magnitude of the quantity

Examples of scalars are ____, ________, _____

What is the formula linking acceleration, initial velocity, final velocity, and time taken?

• F= ma

• V= u+at

Sketch a velocity-time graph for an object with constant acceleration. (Just draw a line )
