forces and motion - speed and acceleration

1. Forces and
Motion
Forces and Energy

2. Explore how things move,
learn what speed means,
and compare the motion of
different animals and
objects
Lesson
Objective

4. Setup: Mark two points in
the classroom/playground
(start and finish line).
Activity: Students move
between the two points in
different “modes”:
Slow walk 🐢
Normal walk 🚶
Fast walk/jog 🏃
Hopping 🦘
Crawling 🐾
Speed walk
Challenge

5. Discussion:
Which was
fastest? How
does the type of
motion change
the speed?
Speed walk
Challenge

6. SPEED
Ishowfastanobject
changes over time
Motion
is a change in an
object’s position

7. WARM-
UP
1.Walking straight at
the same speed →
velocity.
2.Start walking
faster, slower, or
turn left/ right →
acceleration.

ACCELERA
TION
is the speed
and
direction of
an object.
The same unit
of
speed
Example
when a
moving
object speeds up,
slows down or
changes
direction.
Example
How fast an
object

10. FORCES CHANGE
MOTION
A force is any push or pull
A force can cause an object
to start moving or change
direction.
It cause an object to speed
up, slow down or stop.

11. Forces change
motion
•The acceleration of
an object depends
on the
amount of force that
acts upon the
object.
• A greater force gives
an object a greater

12. Forces Change
Motion
Acceleration depends on the
weight of the object.
•If you apply the same
force to objects with
different
weights, the greater
weight accelerates
more slowly.
