- What is another thing that a force can change
The direction of an object (for example a basketball)
- What can forces also change
Speed (golf club and ball)
What are forces measured in
Newtons
Why are forces measured in newtons
Because sir Isaac newton discovered gravity
What do we use to show the size and direction of an object
Arrows
1 newton is the weight of a ….
Apple (0.1kg has the weight of 1N
What is a vector
Quantities that have both size and direction also (magnitude)
What are different examples of forces
Friction, gravity, buoyancy drag/upthrust, magnetism, electro static, water tension
What does every force have
An equal and opposite reaction force
What is an equilibrium
When opposing forces are balanced
What was Newton’s first law
If the forces which act on an object are balanced then the object will either stay still or continue to move at a steady speed ( constant speed)
Look at the homework section
