Flashcards in Velocity And Distance Time Graph's Deck (18):
1

What does the gradient of a distance time graph tell you?

how fast your object is travelling

2

What does gradient equal?

Speed

3

What is acceleration?

Acceleration is how quickly velocity is changing

4

What is the formula for acceleration?

Change in velocity
Acceleration=____________________

Time taken

5

What is the unit for acceleration?

M/s (2)

6

What is the difference between speed and velocity?

Speed is just how fast you're going with no regard to direction.

Velocity however must have the directions specified

7

What does gradient equal in a velocity time graph?

Gradient = acceleration

8

What is gravitational force?

Gravitational force is the force of attraction between all masses

9

What two important effects does gravity have on all matters?

1) on the surface of the planet it makes all things accerlate to the ground

2) it gives everything a weight

10

What is mass and what is weight?

Mass is just the amount of stuff in an object for any given object to this will have the same value anywhere in the universe

Weight is caused by the pull of the gravitational force

11

What is weight measured in?

Weight is a force measured in newtons

12

How is weight measured?

It is measured using a spring balance or newton metre

13

Mass is not a force. What is it measured in and with?

Mass is measured in kilograms with a mass balance

14

What is the equation for weight, mass and gravitational field strength?

Weight= mass X gravitational field
Strength

15

What is the value of the gravity strength on earth and on the moon?

Earth = 10 N/kg

Moon= 1.6 N/kg

16

What are the units of acceleration mass and weight

Acceleration = m/s (2)

Mass= kg

Weight= N

17

A car goes from 0 to 30 m/s (2) in 6 seconds. Calculate its acceleration

(30-0)
________ = 5 m/s (2)

18

Name the force that keeps the earth orbiting around the sun
