Y10 TERM 1 - Motion Flashcards
1
Q
Distance time graphs
A
speed = distance / time
s = d / t
2
Q
Average speed
A
total distance / total time taken
3
Q
Instantaneous speed
A
Speed a at a certain point
4
Q
4 Types of motion
A
- Acceleration
- Deceleration
- Constant speed
- Stationary
5
Q
Gradient of a graph
A
gradient = rise / run
gradient of graph = speed velocity
6
Q
Velocity - time graphs
A
acceleration = change in velocity / time
a = v - u / t
acceleration = gradient of a line on a velocity - time graph
- a = acceleration
- t = time
- v = final velocity
- u = initial velocity
7
Q
Constant speed equation
A
speed = distance / time
8
Q
Acceleration equation
A
a = v - u / t
9
Q
Deceleration equation
A
v2 = u2 + 2as
10
Q
Scalers
A
- scaler - a quantity that has magnitude ( number ) SCALERS: - speed - distance - time -voltage - resistance
11
Q
Vectors
A
- vectors - a quantity that has magnitude + direction VECTORS - velocity - displacement - acceleration - force - current
