Physics 1.4 Demonstrate understanding of mechanics in one dimension
Subject content
Make sure you have up-to-date course notes. Use them, and if you haven't got them see your teacher. The topics you may be tested on are:
- Phenomena, concepts, and principles about motion and force:
- vectors in one dimension:
- addition
- subtraction
- motion:
- distance
- speed (instantaneous, average, and constant)
- displacement
- velocity (average and constant)
- positive and negative acceleration (constant) Interact with this simulation to demonstrate important principles of motion with constant acceleration.
- motion graphs and the interpretation of their gradients and areas.
Need help with interpreting time graphs?
Check out the tutorial on motion of objects in one dimension.
Try out some practice in measuring distance, speed, and time. - force:
- mass
- weight
- acceleration due to gravity
- balanced and unbalanced forces
- free body force diagrams
- pressure.
- vectors in one dimension:
- Phenomena, concepts, and principles about work, energy, and power:
- work and power
- gravitational potential energy
- kinetic energy
- conservation of mechanical energy in free fall situations.
- Relationships:
- Formulae can express the components of a relationship in a simplified way. Here are common components of a formula and a typical unit of measure in brackets:
- v = velocity (ms–1)
- d = distance (m)
- t = time (s)
- a = acceleration (ms–2)
- F = force (N)
- Fnet = net (or resultant) force (N)
- m = mass (kg)
- P = power (W)
- E = energy (J)
- EP = potential energy (J)
- Ek = kinetic energy (J)
- h = height (m)
- W = work (J)
means "change in"
Fnet = ma
W = Fd
