Motion

Front

What is the difference between velocity and speed?

Back

Velocity is speed with a direction.

Front

How is speed defined in physics?

Back

Speed is defined as distance divided by time (Speed = Distance/Time).

Front

What type of motion is described as moving in a circular path at a constant speed?

Back

Uniform Circular Motion.

Front

What is the term for the rate of change of velocity?

Back

Acceleration.

Front

What is the equation for acceleration?

Back

a = Δv/t, where Δv is the change in velocity and t is the time taken.

Front

What is the unit of speed in the International System of Units (SI)?

Back

Meters per second (m/s).

Front

What does a positive acceleration indicate about an object's motion?

Back

A positive acceleration indicates that the object is speeding up.

Front

What does a negative acceleration (deceleration) indicate about an object's motion?

Back

A negative acceleration indicates that the object is slowing down.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What is the difference between instantaneous speed and average speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time, while average speed is the total distance traveled divided by the total time taken.
