3rd Form Physics force & gravity

A force is a ____ or a ____

• push or a pull

• scaler or a vector

• right or a wrong

• strength or a weakness

Which of the following is NOT a force?

• Pounds

• Metres per second

What is the resultant force of the trolley?

• 2 N to the right

• 10 N to the left

• 30 m/s² to the right

• 30N to the right

What is the resultant force?

• 4 N to the right

• 20 N to the left

How do you calculate the force acting on an object?

• mass x acceleration

• weight / acceleration

• mass divided by acceleration

• mass x speed

Acceleration is .....

• the change of force with time

• the change of speed with distance

• the change of speed with time

• the change of mass with time
