What is the formula to calculate acceleration?
acceleration = final velocity / time
acceleration = (final velocity - initial velocity) / time
acceleration = (final velocity * initial velocity) / time
acceleration = (final velocity + initial velocity) / time
Define uniformly accelerated motion.
Motion of an object with no acceleration
Motion of an object with random acceleration
Motion of an object with deceleration
Motion of an object moving in a straight line with constant acceleration.
How is velocity related to acceleration in uniformly accelerated motion?
Velocity and acceleration are inversely proportional in uniformly accelerated motion.
Velocity and acceleration have a sinusoidal relationship in uniformly accelerated motion.
Velocity and acceleration are directly proportional in uniformly accelerated motion.
Velocity and acceleration are not related in uniformly accelerated motion.
State the equation of motion for uniformly accelerated motion.
s = ut + at^2
s = ut + (1/2)at
s = vt + (1/2)at^2
s = ut + (1/2)at^2
What is the SI unit of acceleration?
m/s^2
km/h^2
m/s
cm/s^2
Explain the concept of free fall in the context of uniformly accelerated motion.
Free fall in the context of uniformly accelerated motion refers to the motion of an object falling solely under the influence of gravity, experiencing a constant acceleration of approximately 9.81 m/s^2.
Free fall occurs only in a vacuum environment.
Free fall is when an object moves upwards due to gravity.
Free fall involves a variable acceleration depending on the object's mass.
How does air resistance affect the motion of an object in free fall?
Air resistance has no effect on the motion of an object in free fall
Air resistance increases the speed of the object in free fall
Air resistance causes the object in free fall to move in a straight line
Air resistance slows down the object in free fall, eventually reaching a terminal velocity where the forces balance out.
What is the difference between velocity and speed in uniformly accelerated motion?
Velocity and speed are interchangeable terms in uniformly accelerated motion.
Velocity includes both speed and direction, while speed only represents the magnitude of motion in uniformly accelerated motion.
Velocity is the scalar quantity in uniformly accelerated motion, while speed is the vector quantity.
Speed includes both speed and direction, while velocity only represents the magnitude of motion in uniformly accelerated motion.
Describe the graphical representation of velocity-time graph for uniformly accelerated motion.
The velocity-time graph is a parabola
The velocity-time graph is a zigzag pattern
The velocity-time graph for uniformly accelerated motion is a straight line sloping upwards.
The velocity-time graph is a horizontal line
Calculate the acceleration of a car that goes from 20 m/s to 50 m/s in 5 seconds.
10 m/s^2
15 m/s^2
25 m/s^2
6 m/s^2
