Intro to Motion Review

Front

What is speed?

Back

Speed is the distance an object moves divided by the time it took to move that distance.

Front

What is displacement?

Back

Displacement is the distance between your initial (starting) position and your final position.

Front

What happens to acceleration when you slow down on a bicycle?

Back

When you slow down, acceleration must be opposite the direction of motion.

Front

What is acceleration?

Back

Acceleration is when an object speeds up, slows down, or changes direction.

Front

What is the velocity of a ball thrown upward when caught at the same height?

Back

The velocity is the same as the initial velocity, which is 40 m/s.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

How does velocity differ from speed?

Back

Velocity includes direction, while speed does not.

Front

What is the unit of measurement for speed?

Back

The unit of measurement for speed is meters per second (m/s).

Front

What does it mean if an object has a constant speed?

Back

It means the object covers equal distances in equal intervals of time.

Front

What is the effect of gravity on a thrown ball?

Back

Gravity will slow the ball down as it rises and accelerate it downwards as it falls.
