AP Physics 1 Semester 1 Exam Review

Front

What is the definition of two-dimensional acceleration?

Back

Two-dimensional acceleration is the slope of a velocity-time graph.

Front

What is the formula for Impulse?

Back

Impulse can be defined as J=F*t or J=Δp.

Front

How do you calculate the horizontal distance traveled by a ball thrown horizontally?

Back

Use the formula: distance = velocity * time. For a ball thrown at 65 m/s from a height of 2.2 m, it travels 43.55 m horizontally.

Front

How many significant figures are in the number 0.998005?

Back

The number 0.998005 has 6 significant figures.

Front

What happens to the momentum of an object when its speed is doubled?

Back

When the speed of an object is doubled, its momentum also doubles.

Front

What is the relationship between position, velocity, and acceleration?

Back

Acceleration is the rate of change of velocity, and velocity is the rate of change of position.

Front

Define momentum in physics.

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

What is the principle of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.

Front

How do you determine the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the displacement of the object.

Front

What is the significance of significant figures in measurements?

Back

Significant figures indicate the precision of a measurement and help convey the uncertainty in the value.
