Forces Revision Flashcards
What is a force?
A force is a push, pull, twist or turn. They can cause changes to occur.
What can a force do?
A force can push or pull and object. It can change the shape of an object and its direction. A force can speed up or slow down an object.
Give 3 examples of non-contact forces
Magnetic forces, electrostatic forces and gravity are 3 examples of no-contact forces.
What is drag?
Drag is the force that opposes the movement of an object.
Give an example of a: Starting Motion
Pedalling a bike

Force =
Mass x Acceleration, M x A, MA
There are two types of forces. What are they?
Contact and Non-Contact
Give examples of a contact force.
Applied forces, buoyancy, friction, drag-air resistance and water resistance, normal
Give examples of a non-contact force.
Gravity, electrostatic, magnetic, (nuclear)
