Solutions to Question 2 Sheet 4
Maximum Height, v = 0; s = 80 ms-1; a = -10 ms-2
We can use v2 - u2 = 2as
02 - 802 = 2(-10)s ; -6400 = -20 s
s = 320m
Displacement and total distance travelled after 2,4,6,8,10,12,14 and 16 seconds
We can indeed use s = ut

1).Newton's Universal Law of Gravitation
Every particle in the universe attracts every other particle by a force that is directly proportional to the
product of the masses of the two particles and inversely proportional to t
POST BAC LECTURE 10
MOMENT OR TORQUE
The MOMENT or TORQUE of a force about a point of rotation or axis is the product of the force and the
perpendicular distance between the line of action of the force and the point or axis.

POST BAC LECTURE 7
WORK AND ENERGY
Work is scalar quantity. It is the product of the force (F) and the magnitude of the displacement (d)
parallel to it.
In general the force may not be applied parallel to the displacement but at some angle t

MOMENTUM AND COLLISIONS.
1).DEFINITION OF MOMENTUM
Momentum (P) is a vector. It is the product of the mass (m) plied by the velocity (v).
P = m v (1)
2).Newton used momentum to define force. Force is the rate of change of momentum.

1). Kinematics of uniform circular motion
2). Circular motion
Many students find this difficult to understand but it is in fact relatively simple. Consider an
object tied to a string being rotated in a vertical circle wi

1).Whereas Kinematics addresses how objects move, Dynamics addresses why objects move.
Newton's Laws of Motion are fundamental to the study of Dynamics.
2). Dynamics introduces the concept of FORCE. The average layperson has a

To define and indicate to students the need for Physics in their program. Introduce and give a
brief description of the forces in nature.

Here the particle is not moving along one axis alone. Movement has components along the x
axis as well as along the y axis (Fig. 1). We have to add the two vectors.

The total energy ET is given by:
ET = 1/2 kx2 + 1/2 mv2
At the amplitude x = A and v = 0 so
ET = 1/2 kA2
