Rectilinear Motion

What is speed in rectilinear motion?

• Speed in rectilinear motion is the force applied to an object moving in a curve

• Speed in rectilinear motion is the acceleration of an object in a straight line

• Speed in rectilinear motion is the rate at which an object changes its position along a straight line.

• Speed in rectilinear motion is the distance covered by an object in a circular path

Define acceleration in rectilinear motion.

• The distance traveled by an object

• Rate of change of velocity with respect to time.

• The time taken for an object to move

• The force acting on an object

Explain the concept of Distance-Time Graphs.

• Distance-Time Graphs show how distance changes over speed, with slope indicating time and area under the graph representing total distance.

• Distance-Time Graphs show how distance changes over time, with slope indicating speed and area under the graph representing total distance.

• Distance-Time Graphs show how speed changes over distance, with slope indicating time and area under the graph representing total speed.

• Distance-Time Graphs show how time changes over distance, with slope indicating speed and area under the graph representing total time.

Describe Velocity-Time Graphs in rectilinear motion.

• Velocity-Time Graphs show temperature changes over time

• Velocity-Time Graphs in rectilinear motion depict how velocity changes over time, with slope representing acceleration and area under the graph representing displacement.

• Velocity-Time Graphs represent angular motion

• Velocity-Time Graphs have no relation to acceleration

What are the Equations of Motion used in rectilinear motion?

• v = u + at, s = ut + 0.5at^2, v^2 = u^2 + 2as

• v^2 = u^2 + as

• s = ut + at^2

• v = u + 2at

Differentiate between Uniform and Non-uniform Motion.

• Uniform motion involves varying speed and unequal distances covered in equal time intervals.

• Uniform motion involves constant speed and equal distances covered in equal time intervals, while non-uniform motion involves varying speed and unequal distances covered in equal time intervals.

• Non-uniform motion involves constant speed and equal distances covered in equal time intervals.

• Uniform motion involves constant speed and unequal distances covered in equal time intervals.

How is speed calculated in rectilinear motion?

• Speed = Distance + Time

• Speed = Distance / Time

• Speed = Time / Distance

• Speed = Distance x Time

What is the formula for acceleration?

• a = (v_f - v_i) / t

• a = v_f - v_i * t

• a = v_f * v_i / t

• a = (v_f + v_i) / t

How do you interpret a Distance-Time Graph?

• By counting the number of lines on the graph

• By looking at the color of the graph

• By measuring the width of the graph

• By analyzing the slope of the graph and understanding the relationship between time and distance.

Discuss the significance of Velocity-Time Graphs.

• Velocity-Time graphs determine the color of an object

• Velocity-Time graphs show the temperature changes of an object

• Velocity-Time graphs are significant as they provide a visual representation of an object's motion, allowing for easy analysis of acceleration, deceleration, and displacement.

• Velocity-Time graphs are used to measure the weight of an object
