What do you need to find the net force in a problem?

• Neither mass nor acceleration

• Both mass and acceleration

• Only the acceleration

• Only the mass

What is the other way to find the net Force?

• There is NOT another way. You must use F=ma

• F applied + F friction

• F applied - F friction

• Just multiple mass x acceleration

If the applied force is 70 Newtons and the net force is 48 Newtons, what is the force of friction?

• 100 Newtons

• 70 Newtons

• 48 Newtons

• 22 Newtons

How do you calculate the force of friction if you know the applied force and the net force?

• Divide the applied force by the net force

• Multiply the applied force by the net force

• Subtract the net force from the applied force

• Add the applied force and net force

In the cart problem, what is the net force if the mass is 50 kg and the acceleration is 3 m/s²?

• 50 Newtons

• 600 Newtons

• 450 Newtons

• 150 Newtons

What is the force of friction if the applied force is 600 Newtons and the net force is 150 Newtons?

• 600 Newtons

• 150 Newtons

• 450 Newtons

• 300 Newtons
