Resultant force indicates

Acceleration or deceleration

Acceleration's relationship to resultant force

Directly proportional

Acceleration's relationship to mass

Inversely proportional

Newton's Second Law formula

F=m×aF = m \times a

Zero resultant force means

Constant speed, no acceleration

Effect of larger resultant force

Larger acceleration

Heavier object with same force experiences

Lower acceleration

Same mass, higher force gives

Greater acceleration

Same force, higher mass gives

Lower acceleration

As force increases, acceleration

Increases

As mass increases, acceleration

Decreases

Inertial mass definition

Measure of difficulty to change velocity

Inertial mass formula

fa\frac{f}{a} or forceacceleration\frac{\text{force}}{\text{acceleration}}
