What is the formula for calculating velocity?

• velocity = time / (final position - initial position)

• velocity = (final position + initial position) / time

• velocity = distance / time

• velocity = (final position - initial position) / time

Define acceleration in terms of kinematics.

• Acceleration is the integral of velocity with respect to time.

• Acceleration is the speed of an object.

• Acceleration is the derivative of velocity with respect to time.

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

Explain the difference between speed and velocity.

• Speed is a vector, velocity is scalar.

• Speed is measured in meters per second, velocity is measured in kilometers per hour.

• Speed is scalar, velocity is vector.

• Speed and velocity are the same thing.

How is displacement different from distance?

• Displacement is a scalar quantity, while distance is a vector quantity.

• Displacement is measured in kilometers, while distance is measured in meters.

• Displacement is always positive, while distance can be negative.

• Displacement considers direction, while distance does not.

What is the equation for calculating average speed?

• Average Speed = Total Distance x Total Time

• Average Speed = Total Time / Total Distance

• Average Speed = Total Distance - Total Time

• Average Speed = Total Distance / Total Time

Describe the concept of uniform motion.

• Uniform motion involves the object changing direction constantly.

• Uniform motion is the movement of an object in a circular path at varying speeds.

• Uniform motion is characterized by the object accelerating and decelerating randomly.

• Uniform motion refers to the movement of an object in a straight line at a constant speed.

What is the formula for calculating acceleration?

• acceleration = (final velocity - initial velocity) * time

• acceleration = (final velocity + initial velocity) / time

• acceleration = (final velocity * initial velocity) / time

• acceleration = (final velocity - initial velocity) / time

Explain the meaning of a negative acceleration.

• Negative acceleration means the object is at rest.

• Negative acceleration means the object is speeding up.

• Negative acceleration means the object is moving at a constant speed.

• Negative acceleration means the object is slowing down.

What is the relationship between time and distance in kinematics?

• distance = speed x time

• distance = speed - time

• distance = speed + time

• distance = time / speed

How does acceleration affect an object's motion?

• Acceleration changes the velocity of an object over time.

• Acceleration makes an object invisible

• Acceleration has no effect on an object's motion

• Acceleration causes an object to shrink in size
