Speed, Velocity, Acceleration

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

Define velocity in terms of speed and direction.

Back

Velocity = Speed + Direction

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

If a car travels 60 kilometers in 1 hour, what is its speed?

Back

60 km/hr

Front

True or False: If an object is slowing down, it is accelerating.

Back

True

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What happens to the velocity of an object if it is accelerating in the opposite direction of its motion?

Back

The velocity of the object decreases.

Front

If a car is moving at a constant speed of 50 km/hr, what is its acceleration?

Back

0 m/s² (no acceleration) because the speed is constant.

Front

What is the unit of measurement for speed in the metric system?

Back

Meters per second (m/s) or kilometers per hour (km/hr).
