AQA Force and Motion Presentation

1. Forces and Motion

2. The gradient of a distance – time
graph is equal to the speed of the
object

3. What is the speed of each of the
sections?

4. Velocity is speed in a stated direction

5. Acceleration is how quickly velocity
changes per second

6. A bus accelerates from 5 m/s to 25
m/s in 10s. What is the acceleration
of the bus?

7. A lizard accelerates from 8 m/s to 20 m/s
in 4 seconds. What is the lizard’s average
acceleration?

8. Acceleration is the gradient of a
velocity time graph

9. Calculate the acceleration in sections
A,B and C – Try this one yourself

10. The area underneath a velocity – time
graph is equal to the distance
travelled
Split area
into
rectangles
and
triangles

11. What distance has been travelled in
this case?

12. Now its your turn…………………..
What is the
total
distance
travelled by
this object?

13. The acceleration of an object depends
on the objects mass and resultant
force acting on the object

14. A truck has a mass of 2,000kg.
The driving force created by the engine is
3,000 Newtons.
Calculate the acceleration caused by this
force.

15. A guinea pig of mass 1 kg sits on a skateboard
of mass 2kg. If the skateboard is pushed, and
accelerates at 4 m/s/s, how big is the force
pushing it?
