Acceleration (ms^-2):
The definition of acceleration is the change in speed over time.
= change in velocity/time
= final velocity-initial velocity/time
Momentum (Kg ms^-1):
Momentum is defined as the power of a moving object to keep moving. In this example the heavier truck had more power to keep moving, so it caused more damage.
Momentum (P) = mass(m) X velocity(v)
Speed :
In physics, speed is often measured in meters per second. When we travel, we often use miles per hour.
Formula: Rate equals distance divided by time
Rate = Distance/Time
The answer depends on whether the graph is that of speed v time or distance v time.

Acceleration
Momentum is the product of the mass and velocity of an object. Since a golf ball has a much lower mass than an elephant, it would have to have a much higher velocity to achieve the same momentum as an elephant. But it is definitely possible.
Speed, velocity, and acceleration all have momentum.
Rotational speed. Rotational speed is typically used to calculate rotational kinetic energy rather than angular momentum, which is determined by rotational inertia and angular velocity.
You can calculate speed by dividing the force by the mass to get acceleration, and then multiplying the acceleration by time. Speed = acceleration x time.
You may see acceleration mentioned in a momentum problem; but if it's there, it's only purposeis to help you find the object's velocity.All you need to know in order to find momentum is the object's mass and velocity.
Momentum = mass x speed so speed = momentum/mass or V=P/m
The quantities of motion are described by the concepts of speed, velocity, acceleration, and momentum. Speed is the rate of motion, velocity includes speed and direction, acceleration is the rate at which velocity changes, and momentum is the product of an object's mass and its velocity.
The rate of change in velocity is called acceleration.
Average acceleration = Change in speed/time so Time = Change in speed/Average acceleration
To find speed using acceleration and time, you can use the formula: speed acceleration x time. Simply multiply the acceleration by the time to calculate the speed.
Acceleration = (change in speed) divided by (time interval)
An object's momentum depends on its mass, its speed, and the direction it's moving. If you know these numbers, you can calculate the momentum on your own. You don't need no scientist.
To calculate initial speed (also known as initial velocity), use the following formula: initial speed = (final speed - acceleration*time). You will need to know the final speed, acceleration, and time to calculate the initial speed accurately.
