Uniformly Accelerated Motion (UAM)

Front

What is Uniformly Accelerated Motion (UAM)?

Back

Uniformly Accelerated Motion (UAM) refers to motion in which an object experiences a constant acceleration, meaning its velocity changes at a consistent rate over time.

Front

What is the formula for calculating distance in uniformly accelerated motion?

Back

The formula is: d = v_i * t + 0.5 * a * t^2, where d is distance, v_i is initial velocity, a is acceleration, and t is time.

Front

What is the SI unit of acceleration?

Back

The SI unit of acceleration is meters per second squared (m/s²).

Front

What does a negative acceleration indicate in uniformly accelerated motion?

Back

A negative acceleration indicates that the object is decelerating or slowing down.

Front

If an object starts from rest and accelerates at 5 m/s², what is its velocity after 4 seconds?

Back

Velocity = initial velocity + (acceleration * time) = 0 + (5 m/s² * 4 s) = 20 m/s.

Front

What is the relationship between velocity, acceleration, and time in uniformly accelerated motion?

Back

The relationship is given by the equation: v = v_i + a * t, where v is final velocity, v_i is initial velocity, a is acceleration, and t is time.

Front

What is the significance of the area under a velocity-time graph in uniformly accelerated motion?

Back

The area under a velocity-time graph represents the displacement of the object during that time interval.

Front

How do you calculate the final velocity of an object in uniformly accelerated motion?

Back

Final velocity can be calculated using the formula: v = v_i + a * t.

Front

What is the effect of increasing acceleration on the distance traveled by an object?

Back

Increasing acceleration results in a greater distance traveled over the same time period, as distance is proportional to the square of time when acceleration is constant.

Front

What is the formula to calculate the time taken to stop an object under uniform acceleration?

Back

Time can be calculated using the formula: t = (v_f - v_i) / a, where v_f is final velocity (0 for stopping), v_i is initial velocity, and a is acceleration.
