Exploring Motion in Physics

What are the three main types of motion?

• Linear motion, rotational motion, oscillatory motion

• Cyclic motion, random motion, uniform motion

• Translational motion, vibrational motion, periodic motion

• Static motion, dynamic motion, linear acceleration

Define translational motion with an example.

• A bird flying in circles in the sky.

• A person standing still in a room.

• An example of translational motion is a car driving straight down a road.

• A ball rolling down a hill.

What is the difference between speed and velocity?

• Speed includes direction, while velocity does not.

• Velocity measures distance only.

• Speed is always greater than velocity.

• Speed is scalar; velocity is vector (includes direction).

How is average speed calculated?

• Average speed = Total Distance + Total Time

• Average speed = Total Distance / Total Time

• Average speed = Total Time / Total Distance

• Average speed = Distance / Time Squared

What is instantaneous velocity?

• Instantaneous velocity is the change in speed without regard to direction.

• Instantaneous velocity is the average speed over a long period.

• Instantaneous velocity is the total distance traveled over time.

• Instantaneous velocity is the rate of change of position with respect to time at a specific instant.

Explain the concept of acceleration.

• Acceleration is the distance traveled by an object over time.

• Acceleration is the rate of change of velocity over time.

• Acceleration is the speed of an object at a given moment.

• Acceleration is the force applied to an object divided by its mass.

What is the formula for calculating acceleration?

• a = v_i / t

• a = v_f + v_i

• a = (v_f * v_i) + t

• a = (v_f - v_i) / t

How does uniform acceleration differ from non-uniform acceleration?

• Uniform acceleration occurs only in a straight line.

• Non-uniform acceleration is always faster than uniform acceleration.

• Uniform acceleration can change direction while maintaining constant speed.

• Uniform acceleration has constant acceleration, while non-uniform acceleration has varying acceleration.

What does a speed-time graph represent?

• A speed-time graph shows the distance traveled over time.

• A speed-time graph indicates the total time taken for a journey.

• A speed-time graph represents the acceleration of an object.

• A speed-time graph shows how speed changes over time.

How can you determine acceleration from a velocity-time graph?

• Acceleration can be found by averaging the velocity values.

• Acceleration is determined by the area under the curve.

• Acceleration is the total distance divided by time.

• Acceleration is determined by the slope of the velocity-time graph.
