Fall 24 Physics Exam

Front

What is the formula for calculating speed?

Back

Speed = distance/time

Front

When two objects collide, how does the force of impact compare between them?

Back

The force of impact is the same for both.

Front

How do you calculate the distance traveled by an object that accelerates uniformly?

Back

Use the formula: distance = (initial velocity + final velocity) / 2 * time.

Front

What is the momentum of an object?

Back

Momentum = mass * velocity.

Front

If a skateboard has a momentum of 15 kg m/s and a mass of 5 kg, what is its speed?

Back

Speed = 3 m/s.

Front

What is the radius of the Earth?

Back

The radius of the Earth is approximately 6,400 km.

Front

How do you calculate the time it takes for a satellite to orbit the Earth?

Back

Time = distance/speed.

Front

What is the speed of a satellite in low Earth orbit?

Back

Approximately 8 km/s.

Front

How far does a satellite travel in one complete orbit around the Earth?

Back

Circumference = 2 * π * radius.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

Force = mass * acceleration.
