100

Calculate the speed for a car which covers a distance of 220km in 2 hours.

Speed = 110km/h

100

In a state of rest or moves at a constant velocity unless it experiences an unbalanced force.

Inertia  and/or

Newtons First Law

100

Give the formula for FORCE.

Force = mass x acceleration

100

Change in speed with direction.

Velocity

100

Identify the element

Fe

Iron

200

Calculate the distance covered by a train that is travelling at 110km/h for 4.5 hours. 


D = S x T

= 110 x 4.5

= 495 km

200

The acceleration of an object is dependent on the applied force and mass of the object. 

Which law applies?

Newtons Second Law

200

Give the acceleration for a car which experiences a force of 120 000 N and has a mass of 1500kg.

a = F/m

a = 120 000 /1500

a = 80km/h-2

200

An increase in speed/velocity over time.

Acceleration
200

NaCl

a) Identify the compound

b) Give the common name for the above compound.

Sodium chloride

Salt

300

Give the mass of a train which experiences a force of 420 000 N and has an acceleration of 10m/s.

m = F/a

m = 420 000 / 10

m = 42 000kg

300

Every action has an equal yet opposite force. 

1) Which law applies here?

2) Identify a situation where this occurs.

1) Newtons 3rd Law

2) Sitting down, Swimming, Standing on bathroom scales.

300

Give the formula for 

Force? 

Acceleration?

Mass?

Force = mass x acceleration

Acceleration = Force/mass

Mass = Force /acceleration

300
