- Speed = distance / time
m/s= m/s
- Gradient of a distance time graph- speed= change in distance/ time taken for change
for example 50-0 / 10-0 = 50 / 10 = 5m/s
- Velocity is speed in a given direction
- Acceleration occurs as an object changes velocity
Acceleration= change in velocity / time taken for change
m/s/s= m/s / s - Understand velocity time graph
area under line is distance traveled
- triangles and rectangles
- triangle = 1/2 x base x height
gradient of the line on a velocity time graph is used for acceleration
- Resultant force is when two objects interact they exert equal and opposite forces on each other.
-All the forces acting on an object can be described be a single force that has the same effect as all the forces acting together. - Resultant force N = Mass kg x acceleration m/s/s
- Stopping distance = thinking distance + braking distance
- Braking distance can be increased by more mass, speed of…
