Which of the following are scalar quantities
Energy
Displacement
Electrical resistance
Force
Which of the following are vector quantities
Work
Current
Velocity
Acceleration
A car has travelled 6 Km East, followed by 3 Km east in 2 mins.
Calculate the cars speed and velocity.
A car reached a speed of 60 Km/S from rest in 2 mins. Its acceleration is
1 Km/S2
2 Km/S2
0.5 Km/S2
0.5 Km/S
Force is defined as
(a)
Contact force
is measured in Joules
occurs between objects in physical contact
such as gravity
occurs between objects not in physical contact
Distance force
Measured in Newtons
occurs between objects in physical contact
Such as friction
Occurs between objects not in physical contact
Power
is measured in Newtons
is the rate of work
is the product of force and velocity
is the product of force and displacement
Newtons first law states that
a moving object can randomly change speed
acceleration is dependent on the force
for every action there is a reaction
A stationary object will only move if a force acts on it
Newtons second law states that
Acceleration is independent on the force applied
Acceleration is directly proportional to mass
Acceleration is inversely proportional to mass
Acceleration is dependent on the force applied
