45 m/s² is the... 

• Mass

• Force 

• Acceleration

• weight

Rearrange the force equation to calculate acceleration. (f=ma)

• acceleration = force ÷ weight

• acceleration = force x weight

• acceleration = force x mass

• acceleration = Force ÷ mass

What is the force if the mass is 50 kg and the acceleration is 900 m/s2?

• F = 50 x 900 = 45000 N

• F = 50 ÷ 900 = 0.56N

• F = 900 ÷ 50 = 18 N

Rearrange the force equation to calculate mass. (f=ma)

• mass = force x acceleration

• mass = Force ÷ acceleration

• mass = acceleration x mass
  

What is the force if the mass is 20 kg and the acceleration 80 m/s2?

• F = 80 ÷ 20 = 4N

• F = 20 x 80 = 1600 N

• F = 20 ÷ 80 = 0.25N

What is the acceleration if the force is 50 N and the mass is 100 kg?

• a = 100 ÷ 50 = 2m/s²

• a = 100 x 50 = 5000 m/s²

• a = 50 ÷ 100 = 0.5 m/s²
