Midterm 24-25 Review

Front

What does a constant speed graph look like for a bicyclist moving away from an observer?

Back

A straight line with a positive slope, indicating constant distance over time.

Front

At which point do two runners have the same position on a distance-time graph?

Back

The point where their lines intersect, indicating they are at the same distance at the same time.

Front

What is the formula for calculating potential energy (PE)?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

If a ball has 17 J of kinetic energy and 25 J of mechanical energy, how do you find its height?

Back

Use the formula: Potential Energy (PE) = Total Mechanical Energy - Kinetic Energy. Then, solve for height using PE = mgh.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

How does the distance from the Sun affect gravitational force?

Back

Gravitational force decreases with increasing distance; closer distance results in a stronger gravitational pull.

Front

What is kinetic energy and how is it calculated?

Back

Kinetic energy is the energy of motion, calculated using the formula KE = 0.5mv², where m is mass and v is velocity.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law, F = ma, where F is force, m is mass, and a is acceleration.

Front

What happens to gravitational force when Earth is closer to the Sun?

Back

The gravitational force is slightly larger when Earth is closer to the Sun.

Front

What is the significance of a straight horizontal line on a distance-time graph?

Back

It indicates that the object is at rest, with no change in distance over time.
