1. The car's tachometer will increase. The tachometer measures the engine's revolutions per minute (RPM). When the car is accelerating, the engine will need to work harder and the RPM will increase.
2. The car's speedometer will increase. The speedometer measures the car's speed in miles per hour (MPH). When the car is accelerating, the speedometer will increase.
3. The car will move forward more quickly. This is the most obvious sign that a car is accelerating.
In addition to these three signs, you may also feel the car's engine revving higher and the car's body vibrating more. These are all signs that the car is accelerating.
