A car is accelerating forward on a road. The arrows in the image represent four different forces.

Which forces are equal, and why?

• Forces W and Y; the car is moving forward

• Forces W and Z; the car resists gravity

• Forces X and Y; the car is accelerating

• Forces X and Z; the car remains on the ground
