Midterm KInematics Review

Front

What is the formula for calculating horizontal velocity?

Back

Horizontal velocity (v) can be calculated using the formula: v = d/t, where d is the distance traveled and t is the time taken.

Front

Define acceleration in the context of motion.

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be positive (speeding up) or negative (slowing down).

Front

What does a horizontal line on a velocity-time graph indicate?

Back

A horizontal line on a velocity-time graph indicates that the object is moving at a constant velocity.

Front

What type of motion is exhibited by an object that is falling freely under the influence of gravity?

Back

The object is exhibiting acceleration (speeding up) due to the force of gravity.

Front

How do you calculate acceleration when given initial and final velocity?

Back

Acceleration (a) can be calculated using the formula: a = (v_f - v_i) / t, where v_f is the final velocity, v_i is the initial velocity, and t is the time taken.

Front

What is the significance of a negative acceleration value?

Back

A negative acceleration value indicates that the object is slowing down.

Front

Explain the concept of constant velocity.

Back

Constant velocity means that an object is moving at the same speed in a straight line, with no change in direction or speed.

Front

What is the relationship between distance, speed, and time?

Back

The relationship is given by the formula: distance = speed × time.

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration and terminal velocity.

Front

How can you determine the acceleration of an object from a velocity-time graph?

Back

The acceleration can be determined by calculating the slope of the line on the velocity-time graph.
