Motion along a straight line by a car refers to the movement of a car in a single direction without any change in direction or turning.
The motion of a car along a straight line can be affected by factors such as the car's speed, acceleration, friction, and external forces like wind resistance or gravity.
The motion of a car along a straight line can be measured using various tools such as a speedometer, odometer, or GPS system. These tools measure the car's speed, distance traveled, and direction of movement.
Speed refers to the rate at which an object, in this case a car, is moving. Velocity, on the other hand, takes into account the direction of the car's movement as well as its speed. So, a car traveling at a constant speed but changing direction has a different velocity at each point of its motion.
Newton's first law of motion states that an object at rest will remain at rest and an object in motion will continue in motion with a constant velocity unless acted upon by an external force. This applies to a car's motion along a straight line as the car will continue moving in the same direction and speed unless an external force, such as friction or a change in speed, is applied to it.
