Physical Science Semester 1 Review 1

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction. It can be zero if the object returns to its starting point.

Front

If a jogger runs around a 400 m track twice and returns to the starting point, what is his displacement?

Back

0 m

Front

How do you calculate time when speed and distance are known?

Back

Time = Distance / Speed.

Front

How long will it take a Pony Express rider to travel 24,000 m at a speed of 12 m/s?

Back

2,000 s

Front

What is the formula to find mass using force and acceleration?

Back

Mass = Force / Acceleration.

Front

If a vehicle exerts a force of 3,500 N while accelerating at 7 m/s², what is its mass?

Back

500 kg

Front

What is the formula to calculate force?

Back

Force = Mass x Acceleration.

Front

What force is needed to accelerate a rocket at 60 m/s² with a mass of 20,000 kg?

Back

120,000 N

Front

How do you convert meters to kilometers?

Back

To convert meters to kilometers, divide the number of meters by 1,000.

Front

Convert 2200 m to kilometers.

Back

2.2 km
