If an object<span> has a net </span>force<span> acting on it, it will accelerate. The </span>object<span> will speed up, slow down or change direction. An </span>unbalanced force<span> (net </span>force<span>) acting on an </span>object<span>changes its speed and/or direction of motion. An </span>unbalanced force<span> is an unopposed</span>force<span> that causes a change in motion.
thus the car would get its speed, and or direction mixed up</span>
It is the ratio of distance an object moves to the amount of time needed to travel the distance.
Option b.
Answer:
Ampere
Explanation:
The ampere is the unit of measurement in the international system. Its equal to a coulomb/second. It can be describe as the rate of charges flowing throught a conductor
Answer:
-1.03 m/s²
Explanation:
Acceleration: This can be defined as the rate of change of velocity. The S. I unit of acceleration is m/s².
Mathematically, acceleration is expressed as
a = (v-u)/t ........................ Equation 1
Where a = acceleration, v = final velocity, u = initial velocity, t = time.
Given: u = 13.60 m/s, v = 7.20 m/s t = 6.2 s.
Substituting into equation 2
a = (7.20-13.60)/6.2
a = -6.4/6.2
a = -1.03 m/s²
Note: a is negative because, the hockey puck is decelerating.
Hence the average acceleration = -1.03 m/s²
Answer:
Options (C) and (F).
Explanation:
Constant speed of an object is represented by the flat segment (a line parallel to the x-axis) on the graph of velocity and time.
In other words, flat segments represents no change in the velocity with respect to the time.
From the graph attached,
Being flat segments, C and F will represent the constant speed.
Therefore, Options (C) and (F) will be the correct options.
