Year 10
Forces & motion 2
Term 4
"HT: Use the equation of motion to find velocity2
USE ONLY v2 – u2 = 2as
State the units & symbols of each component in the equation"
Describe why a falling object reaches terminal velocity
Describe Newton's first law
Explain how an object can be made to change its speed (in terms of forces)
HT: Define Inertia & Inertial Mass
Describe Newton's second law
Explain the relationship between the acceleration of an object and the resultant force
USE & RECALL - Force = mass x acceleration
State the units & symbols of each component in the equation
Explain Newton's Third Law
Give examples of Newton's third law in action
Explain what is meant by "inertial mass"
Explain how to calculate stopping distance
Estimate AND Measure reaction times
State factors effecting reaction times
Explain what happens to the braking distance with changes in speed
Explain how the braking distance can be affected by different factors
"Explain the effect of a braking force on a car wheel's kinetic and thermal energy
Explain the link between the size of a braking force and deceleration
HT: Estimate the forces involved in deceleration of road vehicles"
Explain the problems with large decelerations
