Physics Questions
What is the definition of displacement?
A vector quantity that describes the straight line distance between two points
What does the slope of a line in a position time graph represent?
Average Velocity
What is the definition of the term acceleration?
Rate of change of velocity
The steeper the line of a distance time graph is the a)lower the speed b)greater the speed
Greater the speed
What unit represents acceleration?
m/s²
What is the relationship between displacement, time interval and average velocity of an object travelling in uniform motion?
- When /\d gets larger and /\t is constant, the average velocity gets larger - When /\t gets larger, and /\d is constant, the average velocity gets smaller - When /\av gets larger, the slope position of a position -time (/\d / /\t) graph gets steeper
What is the initial velocity of an object that falls from rest from a tree?
0 m/s
What describes a uniform motion?
Constant Velocity
What is needed to calculate the average velocity of an object?
Displacement and Time
What gives the values required to calculate the time taken to travel a certain distance?
Displacement and Velocity
What is divided by time when calculating the average speed of an object?
Distance
What are the differences between distance and displacement?
Distance is a SCALAR Displacement is a VECTOR
