Kinematics is the study of motion and its causes. In the context of a car's acceleration, kinematics refers to the study of how the car's velocity changes over time due to external forces such as the engine's power and friction from the road.
Acceleration is calculated by dividing the change in velocity by the time it took to change. The formula for acceleration is a = (vf - vi)/t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
Several factors can affect a car's acceleration, such as the power and torque of the engine, the weight of the car, the friction between the tires and the road, and any external forces acting on the car, such as air resistance.
Acceleration is the rate at which an object's velocity changes, while speed is the rate at which an object's distance changes. In other words, acceleration measures how quickly an object is speeding up or slowing down, while speed measures how fast an object is moving at a particular moment.
Yes, a car can have a negative acceleration, also known as deceleration or slowing down. This can happen when the car's velocity decreases over time, such as when the brakes are applied or when the car is traveling uphill against gravity.
