If a car is driving eastward with a constant velocity and then suddenly applies the brakes to decelerate, its acceleration is in the opposite direction of its motion, which would be westward. This is because acceleration is a vector quantity that can act in the direction opposite to the object's motion.
If the speed of a car traveling south is increasing at 5 m/s, then its acceleration is 5 m/sĀ². This acceleration indicates the rate at which the car's velocity is changing per unit time.
There is no acceleration if the car is travelling at a steady 54,000 miles per hour.
Straight line at a constant speed = no acceleration
well as we know that velocity is a vector hence it has magnitude as well as direction. Let us assign sign conventions for direction of velocities in this example: Let eastward velocity be positive and westward be taken as negative. Initial Velocity:-20 Final Velocity:+5 CHange in velocity=Final velocity-Initial Valocity Change in Velocity=5-(-20)=25m/s So change in velocity will be 25m/s
Yes, an object can have velocity and acceleration vectors that point in opposite directions. This typically occurs when the object is slowing down or decelerating. The velocity vector indicates the direction and magnitude of the object's motion, while the acceleration vector indicates the rate of change of the velocity.
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
The acceleration of the car is 0 m/s^2 since it is traveling at a constant speed and not changing its velocity.
The acceleration of a car traveling at a steady speed of 60 mph is zero. Acceleration refers to a change in velocity over time, so a steady speed means there is no change in velocity and therefore no acceleration.
The acceleration of the car is equal to the rate of change of its speed over time. When a car goes from zero speed to a higher speed, it experiences positive acceleration in the direction of its motion.
If something is traveling at a "steady" speed, it can't be accelerating.
If a body moving east experiences an acceleration in the direction of west, it indicates that a force is acting on it in the opposite direction of its velocity. This acceleration would cause the body to slow down or change direction to the west. An external force, like friction or a push from another object, must be responsible for this change in acceleration.
