Physics fall semester review

Front

What is the relationship between velocity and time for an object that accelerates uniformly, moves at constant velocity, and then decelerates?

Back

The graph will show a linear increase in velocity during acceleration, a flat line during constant velocity, and a linear decrease during deceleration.

Front

What does a graph representing an object starting at rest and accelerating uniformly look like?

Back

The graph is a straight line starting from the origin, indicating a constant increase in velocity over time.

Front

What factors affect the size of the gravitational force between two objects?

Back

The gravitational force depends on the masses of the objects and the distance between them.

Front

What happens to the total momentum of two colliding soccer balls?

Back

The total momentum remains constant before and after the collision.

Front

How do you calculate the average time from multiple measurements?

Back

Add all the times together and divide by the number of measurements.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.

Front

Define momentum in physics.

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the formula for calculating gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What does a flat line on a velocity-time graph indicate?

Back

A flat line indicates that the object is moving at a constant velocity.

Front

What is the significance of the area under a velocity-time graph?

Back

The area under the graph represents the distance traveled by the object.
