Motion Graphs

Question 0

Equation linking speed time and distance

Answer 0

Speed= distance/time

Question 1

Distance times graph straight line

Answer 1

Stationary

Question 2

Distance time graph gradient

Answer 2

Steeper the gradient, faster the speed

Question 3

Bouncing ball

Answer 3

As you drop ball GP –> KE
As the ball hits the floor KE –> EP
Some lost as heat and sound
Every bounce some force is lost as energy is lost as waste into surroundings

Question 4

Rolling ball

Answer 4

The larger the distance, the faster the ball rolls as it accelerates

Question 5

Equation linking time acceleration and velocity gain

Answer 5

Acceleration= gain in velocity/time taken

Question 6

Scalar

Answer 6

Magnitude only

Question 7

Vector

Answer 7

Magnitude and direction

Question 8

Distance =

Answer 8

The magnitude of displacement when motion in a straight line in one direction only

Question 9

Unit for acceleration

Answer 9

m/s^2

Question 10

Deceleration

Answer 10

Negative acceleration

Question 11

In a speed time graph area and gradient show

Answer 11

Area under line shows distance

Gradient shows acceleration

Question 12

Speed =

Answer 12

The magnitude if society when motion in a straight line in one direction only

Question 13

Example of scaler

Answer 13

Distance

Question 14

Example of vector

Answer 14

Velocity

Question 15

Equation linking time velocity and displacement

Answer 15

Velocity= displacement/time

Question 16

Equation for average velocity

Answer 16

Average velocity = total displacement/time
