Motion and its Concepts

What is the definition of motion?

• The speed of an object

• Change in position of an object over time

• The weight of an object

• The color of an object

How do you calculate speed?

• Distance divided by time

• Time multiplied by distance

• Distance plus time

• Distance minus time

What is the difference between speed and velocity?

• Distance

• Acceleration

• Direction

• Time

Define velocity and provide an example.

• Velocity is the force exerted by an object. Example: A ball thrown with great force.

• Velocity is the same as speed. Example: A train moving at 100 kilometers per hour.

• Velocity is the rate of change of an object's position with respect to a frame of reference. Example: A car traveling at 60 miles per hour eastward.

• Velocity is the distance traveled by an object in a given time. Example: A person walking at a constant speed.

If an object is moving at a constant speed, what can you say about its acceleration?

• Acceleration is decreasing

• Acceleration is increasing

• Acceleration is constant

• Acceleration is zero

Explain the concept of acceleration.

• Acceleration is the same as speed.

• Acceleration is the force acting on an object.

• Acceleration is the rate of change of velocity with respect to time.

• Acceleration is the distance traveled by an object.

What is the formula to calculate acceleration?

• a = v * t

• a = (v + u) / t

• a = (v * u) / t

• a = (v - u) / t

Give an example of a situation where an object has same speed and velocity.

• Object moving at a constant speed in a curved path

• Object moving at a constant speed in a straight line

• Object moving at a constant speed in a circular path

• Object moving at a variable speed in a straight line

How is average speed different from instantaneous speed?

• Average speed and instantaneous speed are the same thing.

• Average speed is the speed at a specific moment in time, while instantaneous speed is the total distance traveled divided by the total time taken.

• Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed at a specific moment in time.

• Average speed is always faster than instantaneous speed.

Explain the concept of relative motion.

• Relative motion is the calculation of the motion of an object with respect to a particular frame of reference.

• Relative motion is the calculation of the motion of an object in a vacuum.

• Relative motion is the calculation of the motion of an object with respect to a fixed point in space.

• Relative motion is the calculation of the motion of an object without considering any frame of reference.
