Physics Paper 2 AQA - Basic Overview of content

Name an example of a Contact Force

(a)  

A force with both Magnitude and Direction is a (a)   force.

Weight is a force acting on an object due to _______

• Gravity

• Mass

Weight is directly proportional to (a)  

Answer explanation

This is why there is a feeling of weightlessness in space.

- The GFS is lower, therefore you don't experience as much weight.

The (a)   force is the sum of all forces acting on something.

When a force moves an object through a distance; ___ is transferred.

• Energy

• Force

• Force ions

Answer explanation

Hence, the equation

Energy=Force x Displacement

Force ions don't exist.

Which of these are tactics we can use to find resultant force / split apart resultant forces. (2)

• Drawing a scale diagram - tip to tail (usually triangles)

• Splitting a diagonal force into a horizontal and vertical force.

• Drawing a scaled Free Body Force Diagram.

Answer explanation

For both Drawing a Scale Diagram & Splitting a Diagonal Force into components we can draw them as triangles/shapes like this

<--------------------------------------------------------

You will already know the forces for a Free Body Force Diagram

When you apply a force to an object you may cause it to (a)   , compress and bend. (CLUE: what happens when you pull a spring at both ends)

Extension is directly proportional to Force, however, this stops being true at the _____ __ _____________

• Limit of Proportionality

• Limit of Spring Stretch

• Spring no stretchy

• Hooke's Law

A Force / Several Forces can cause an object to rotate, this is called a moment.

A moment is the ______ ______ of a force.

• turning effect

• Hooke's Law

• Rotating-ness
