What is the formula to calculate acceleration?
acceleration = (final velocity * initial velocity) / time
acceleration = (final velocity - initial velocity) / time
acceleration = final velocity / time
acceleration = (final velocity + initial velocity) / time
If an object has an initial velocity of 5 m/s and a final velocity of 15 m/s over a time of 3 seconds, what is its acceleration?
3.33 m/s^2
5.33 m/s^2
2.5 m/s^2
4.67 m/s^2
Explain the concept of uniformly accelerated motion.
Uniformly accelerated motion only occurs in a vacuum.
In uniformly accelerated motion, the object's velocity decreases over time.
The concept of uniformly accelerated motion involves an object moving in a straight line with constant acceleration, where its velocity changes by the same amount in equal time intervals.
Uniformly accelerated motion involves an object moving in a circular path with constant acceleration.
How does acceleration constantis differ from other types of acceleration?
Acceleration constantis is dependent on the object's mass
Acceleration constantis changes direction frequently
Acceleration constantis remains constant over time, unlike other types of acceleration.
Acceleration constantis is always negative
A car accelerates from 20 m/s to 40 m/s in 5 seconds. What is its acceleration?
4 m/s^2
2 m/s^2
6 m/s^2
10 m/s^2
What are the SI units of acceleration?
cm/s
m/s
ft/s^2
m/s^2
km/h^2
State the three equations of motion for uniformly accelerated motion.
s = ut + at^2
v = u + t
v = u + 2at
v = u + at, s = ut + 0.5at^2, v^2 = u^2 + 2as
How does acceleration affect an object's velocity?
Acceleration always increases an object's velocity
Acceleration only affects an object's mass, not its velocity
Acceleration has no effect on an object's velocity
Acceleration affects an object's velocity by changing its speed and/or direction.
What is the acceleration of an object in free fall near the surface of the Earth?
8.33 m/s^2
9.81 m/s^2
5.67 m/s^2
10.25 m/s^2
Explain the relationship between acceleration, velocity, and time in uniformly accelerated motion.
Acceleration is constant in uniformly accelerated motion, so velocity and time do not play a role in the relationship.
Acceleration is the derivative of velocity with respect to time, meaning acceleration affects how velocity changes over time in a consistent manner.
Time is the derivative of acceleration with respect to velocity, meaning time affects how acceleration changes over velocity in a consistent manner.
Velocity is the derivative of acceleration with respect to time, meaning velocity affects how acceleration changes over time in a consistent manner.
