Acceleration Flashcards
In a distance-time graph, the gradient represents?
speed
Speed= ?
Distance
_______
Time
A horizontal line on a distance/time graph means?
The object is stationary
A straight line on a distance-time graph means?
The object is moving at a constant speed.
Velocity is?
Speed with direction
If 2 objects are moving at the same speed in different directions, what happens to their velocity?
Their velocities become different
If an Object’s direction is continuously changing, what happens to the velocity
The velocity is also continuously changing.
What is Acceleration?
The rate of change in velocity
What is deceleration?
When an object is slowing down
Acceleration equation:
Time taken for change
OR
a=v-u
——-
t
On a Speed-Time graph, the gradient represents?
The acceleration
On a Speed time graph, the area under the graph equals?
The distance travelled
Average speed
Total time
Final speed
Total distance
——————– x 2
Total time
OR
Average speed x 2
What is the difference between distance and displacement?
Distance: scalar
Displacement: vector, distance in a given direction
