What is the speed of an object plus its direction?
The speed of an object plus its direction is called velocity. Velocity is a vector quantity that combines the object's speed (magnitude of the velocity) and its direction of motion.
What is the effect on accelerationif we decreasing velocity?
If velocity is decreasing, acceleration is in the opposite direction of the initial velocity. If the velocity is decreasing at a constant rate, the acceleration is negative, causing deceleration. If the velocity is decreasing while changing direction, the acceleration may be a combination of negative and positive components.
State the ways velocity can change?
the velocity of an object changes when it speeds up or slows down.
Does the initial velocity in a projectile is inversely proportional to the range?
No, the initial velocity of a projectile is not inversely proportional to the range. The range of a projectile is determined by a combination of its initial velocity, launch angle, and acceleration due to gravity. A higher initial velocity can lead to a longer range, but it's not a strict inverse relationship.
What would you expect to have the least momentum?
An object with a small mass and low velocity would have the least momentum. Momentum is the product of an object's mass and velocity, so a combination of low mass and low velocity would result in the least momentum.
Velocity is the combination of?
Velocity is measured by a combination of speed and direction.

Do two skaters traveling in different directions at the same speed have the same velocity?
No. Velocity is the combination of a speed and its direction. In order fortwo objects to have the same velocity, they must be moving at the samespeed, and in the same direction.

the velocity of an object changes when it speeds up or slows down.

Do velocity vectors combine with force vectors?
simply: No, Velocity vectors are different to force vectors. One measures velocity and one measures force so you can not simply add/subtract/multiply/divide them together and get something meaningful.
How is it possible for a bicycle to have more momentum than a truck?
While a truck may have more mass than a bicycle, momentum is also influenced by velocity. If the bicycle is traveling at a significantly higher speed than the truck, it can have more momentum due to the combination of its mass and velocity. Momentum is calculated as mass multiplied by velocity, so a lighter object with higher velocity can have more momentum than a heavier object with lower velocity.
Which velocity component changes along the path?
The motion of a projectile is a combination of two motions, a constant speed motion in the horizontal direction, and an accelerated motion in the vertical direction. The velocity component that changes along the path is Vy.
What cause projectile motion?
Projectile motion is caused by the combination of an initial velocity and the force of gravity acting on an object. When an object is launched into the air with an initial velocity, it follows a curved path as it is both propelled forward and pulled downward by gravity. The object's horizontal velocity remains constant, while its vertical velocity changes due to gravity, resulting in a parabolic trajectory.
How do you calculate the change in velocity of an object?
To calculate the change in velocity of an object, you subtract the initial velocity from the final velocity. The formula is: Change in velocity Final velocity - Initial velocity.
