What is the equation that links: force, mass and ______ ?
Force = mass x acceleration
1 of 15
What is the equation that links: speed, time taken and _______?
Speed = change in distance /time taken
2 of 15
What is the equation that links: moment, force and _______?
Moment = force x distance from pivot
3 of 15
What is the equation that links: weight, mass and _________?
Weight = mass x gravitational field strength
4 of 15
What is the equation that links: change in velocity, time and _______?
Change in velocity= acceleration x time
5 of 15

What is Newtons' first law?
An object will only change velocity if there is an unbalanced force acting on it
8 of 15
What is Newtons' second law?
You can work out the acceleration of an object if you know the mass and the force applied
9 of 15
What is Newtons' third law?
For every action there is an equal and opposite reaction
10 of 15
When is an objects resultant force zero?
When the object is stationary or moving at constant speed
11 of 15
What is the effect of resultant force in the opposite direction of an object?
The object will decelerate
12 of 15
What is the effect of a resultant force on an object at rest
It will accelerate in the direction of the resultant force
13 of 15
What happens when mass increases but force stays the same?
Acceleration is smaller
14 of 15
How does an object reach terminal velocity?
When an object falls, air resistance resists its motion. The faster the object falls the bigger the air resistance becomes. Eventually, Air resistance= weight of object and resultant force = zero.
